Need help with simple price x quantity calculation

8 New Member
I have a very simple price times quantity calculation.

The input is STWCORQuant:

Expand|Select|Wrap|Line Numbers
  1. <input name="STWCORQuant" class="contactitalicbold" id="STWCORQuant" onChange="javascript:STWCORPrice();" value="0" size="8" style="text-align: right; font-family: ver">
And the fucntion is STWCORPrice():

Expand|Select|Wrap|Line Numbers
  1. <script language="javascript" type="text/javascript">
  2.  
  3. function STWCORPrice() {
  4.         var price = 0;
  5.         var shipping = 0;
  6.         var total=0;
  7.         var qnty=document.all.STWCORQuant.value;
  8.  
  9.         if (qnty > 49 && qnty < 75){
  10.                     price = 23;
  11.                     shipping = 6.25;
  12.                     }
  13.  
  14.                 else if (qnty > 74 && qnty < 100){
  15.                     price = 17;
  16.                     shipping = 6.25;
  17.                         }
  18.  
  19.                 else if (qnty > 99 && qnty < 200){
  20.                     price = 14;
  21.                     shipping = 6.25;
  22.                         }
  23.  
  24.                 else if (qnty > 199 && qnty < 250){
  25.                     price = 13.75;
  26.                     shipping = 7.75;
  27.                         }
  28.  
  29.         total = (price * qnty)+shipping;        
  30.         document.all.STWCORIssueCost.value= '$ '+ total.toFixed(2);
  31.     }
  32.  
  33. </script>
  34.  
The output is this:

Expand|Select|Wrap|Line Numbers
  1. <td width="15%" id="STWCORIssueCost" Font Class="sidemenutextgrn" align="right">$0</Font></td>
It doesn't work, but looks like it should. When a quantity is input and the box is tabbed out of, nothing happens. I can't tell what is wrong....need help!

Thanks

@acoder
I think, node.nodeValue should work also.

Actually, it wouldn't. You'd need to use firstChild.node Value in place of innerHTML.
