<td><b> Total</b></td><td>
-
Quantity #1 <Input type = 'text' Value ='0' Name ='qty1' >
-
Quantity #2 <Input type = 'text' Value ='0' Name ='qty2'>

Okay now its getting complicated when I put it inside my PHP. Please tell me what did i wrong and why its not computing? - <?PHP
-
$result = mysql_query("select Total from tblEvent_Entity where Cal_ID='{$id}' and Entity ='Organizations' ");
-
$row = mysql_fetch_assoc($result);
-
$TotalOrganizations = $row['Total'];
-
echo "<tr><td width='50%'>Organizations</td><td width='67%'><Input type = 'text' Name ='totalOrganizations' id ='totalOrganizations' value='$row[Total]'
-
onkeyup='if ((document.getElementById('totalOrganizations').match(/^[0-9]+$/) && document.getElementById('totalAgencies').value.match(/^[0-9]+$/)))
-
document.getElementById('Total').value = parseInt(document.getElementById('totalOrganizations').value)) + parseInt(document.getElementById('TotalAgencies').value);
-
else document.getElementById('Total').value = '';>
-
</td></tr>";
-
-
-
$result = mysql_query("select Total from tblEvent_Entity where Cal_ID='{$id}' and Entity ='Agencies' ");
-
$row = mysql_fetch_assoc($result);
-
$TotalAgencies= $row['Total'];
-
echo "<tr><td>Agencies</td><td width='67%'><Input type = 'text' Name ='totalAgencies' id='totalAgencies' value='$row[Total]'
-
onkeyup='if ((document.getElementById('totalAgencies').match(/^[0-9]+$/) && document.getElementById('totalOrganizations').value.match(/^[0-9]+$/)))
-
document.getElementById('Total').value =(document.getElementById('totalOrganizations').value) + parseInt(document.getElementById('totalAgencies').value);
-
else document.getElementById('Total').value = '';>
-
</td></tr>";
-
-
echo "Grand Total <input type = 'text' value ='' name ='Total' id='Total' > ";?>

What's your excuse now? ;)
I have two input box that I wanted to calculate the Total while the user inputing thier numbers on the text box. On my HTML format its works perfectly but when I applied it inside my PHP code it doesn't work anymore. I appreciate your time looking at this. - <?PHP
-
$result = mysql_query("select Total from tblEvent_Entity where Cal_ID='{$id}' and Entity ='Organizations' ");
-
$row = mysql_fetch_assoc($result);
-
$TotalOrganizations = $row['Total'];
-
echo "<tr><td width='50%'>Organizations</td><td width='67%'><Input type = 'text' Name ='totalOrganizations' id ='totalOrganizations' value='$row[Total]'
-
onkeyup='if ((document.getElementById('totalOrganizations').match(/^[0-9]+$/) && document.getElementById('totalAgencies').value.match(/^[0-9]+$/)))
-
document.getElementById('Total').value = parseInt(document.getElementById('totalOrganizations').value)) + parseInt(document.getElementById('TotalAgencies').value);
-
else document.getElementById('Total').value = '';>
-
</td></tr>";
-
-
-
$result = mysql_query("select Total from tblEvent_Entity where Cal_ID='{$id}' and Entity ='Agencies' ");
-
$row = mysql_fetch_assoc($result);
-
$TotalAgencies= $row['Total'];
-
echo "<tr><td>Agencies</td><td width='67%'><Input type = 'text' Name ='totalAgencies' id='totalAgencies' value='$row[Total]'
-
onkeyup='if ((document.getElementById('totalAgencies').match(/^[0-9]+$/) && document.getElementById('totalOrganizations').value.match(/^[0-9]+$/)))
-
document.getElementById('Total').value =(document.getElementById('totalOrganizations').value) + parseInt(document.getElementById('totalAgencies').value);
-
else document.getElementById('Total').value = '';>
-
</td></tr>";
-
-
echo "Grand Total <input type = 'text' value ='' name ='Total' id='Total' > ";?>

Post the client-side generated (HTML) code. Also, remove the unnecessary indents to make the code easier to follow.
Do you get any JavaScript errors?
Can you show me from my sample code what do you mean? Thanks for your help

I mean the code that is generated from your PHP code when you view the source in the browser.

Here it is... -
<tr><td width='50%'>Organizations</td><td width='67%'><Input type = 'text' Name ='totalOrganizations' id ='totalOrganizations' value=''
-
onkeyup='if ((document.getElementById('totalOrganizations').match(/^[0-9]+$/) && document.getElementById('totalAgencies').value.match(/^[0-9]+$/)))
-
document.getElementById('Total').value = parseInt(document.getElementById('totalOrganizations').value)) + parseInt(document.getElementById('TotalAgencies').value);
-
else document.getElementById('Total').value = '';>
-
</td></tr><tr><td>Agencies</td><td width='67%'><Input type = 'text' Name ='totalAgencies' id='totalAgencies' value=''
-
onkeyup='if ((document.getElementById('totalAgencies').match(/^[0-9]+$/) && document.getElementById('totalOrganizations').value.match(/^[0-9]+$/)))
-
document.getElementById('Total').value =(document.getElementById('totalOrganizations').value) + parseInt(document.getElementById('totalAgencies').value);
-
else document.getElementById('Total').value = '';>
-
</td></tr>Grand Total <input type = 'text' value ='' name ='Total' id='Total' >

no wonder it doesn’t work, the onkeyup attribute is not closed, resp. it closes at the first JavaScript quotation mark, rendering the HTML invalid.
my recommendation: use a proper event handler.
Do you mean by doing this (see onkeyup)
<Input type = 'text' Name ='totalAgencies ' id='totalAgenci es' value='$row[Total]'
onkeyup=\"if ((document.getE lementById('tot alAgencies').ma tch(/^[0-9]+$/) && document.getEle mentById('total Organizations') .value.match(/^[0-9]+$/)))
document.getEle mentById('Total ').value =(document.getE lementById('tot alOrganizations ').value) + parseInt(docume nt.getElementBy Id('totalAgenci es').value);
else document.getEle mentById('Total ').value = ''\";>

well, yes. although IMHO inline JavaScript is bad practice.
