Problem with couter stop

I'm having problems with the counter, the function should add a row to a table but should stop when there are 3 row added. In this case its not stopping

what is wrong in the script ?
thanks for any help

var i=0

function addRowToTable() {
if (i == 3)
{
alert("Er kunnen niet meer groepen worden toegevoegd, neem contact op met de RAB");
return;
}

var tbl = document.getElementById('tblSample');
var lastRow = tbl.rows.length;
// if there's no header row in the table, then iteration = lastRow + 1
var iteration = lastRow + i;
var row = tbl.insertRow(lastRow);

if (i == 3)
{
alert("Er kunnen niet meer groepen worden toegevoegd, neem contact op met de RAB");
return;
}

Try running this code in a browser and let me know if this is what you wanted :

Expand|Select|Wrap|Line Numbers

 <HTML>

<BODY>

<TABLE id='tblSample' border=1>

<TR>

    <Th>T1</Th>

    <Th>T2</Th>

</TR>

</TABLE>

</BODY>

<script>
 
function removeRowFromTable() 

{
 
var tbl = document.getElementById('tblSample');

var lastRow = tbl.rows.length;

if (lastRow > 1)tbl.deleteRow(lastRow + i)
 
}
 
var i=0

while(i<3)

    addRowToTable();

function addRowToTable() {
 
var tbl = document.getElementById('tblSample');

var lastRow = tbl.rows.length;

// if there's no header row in the table, then iteration = lastRow + 1

var iteration = lastRow + i;

var row = tbl.insertRow(lastRow);
 
if (i == 3)

{

alert("Er kunnen niet meer groepen worden toegevoegd, neem contact op met de RAB");

return;

}
 
// left cell

var cellLeft = row.insertCell(0);

var textNode = document.createTextNode(iteration);

cellLeft.appendChild(textNode);
 
// right cell

var cellRight = row.insertCell(1);

var el = document.createElement('input');

el.type = 'checkbox';

el.name = 'txtRow';

el.id = 'txtRow' ;

el.size = 40;

cellRight.appendChild(el);

i++;

}

</script>

</HTML>

Hope that helps..

thanks ashsa !

I'v changed the script and it works when I add up a Row. in thos case till its 5, but when I delete a 1, 2 or more Rows, and again add a row It stops because it was already counting till 5, I post the code I'm using.
Do you have any idees?

<HTML>
<BODY>
<TABLE id='tblSample' border=1>
<TR>
<Th>T1</Th>
<Th>T2</Th>
</TR>
</TABLE>
</BODY>
<script>

function removeRowFromTable()
{

var tbl = document.getElementById('tblSample');
var lastRow = tbl.rows.length;
if (lastRow > 1)tbl.deleteRow(lastRow - 1)

}

var i=0
while(i<1)
addRowToTable();
function addRowToTable() {

var tbl = document.getElementById('tblSample');
var lastRow = tbl.rows.length;
// if there's no header row in the table, then iteration = lastRow + 1
var iteration = lastRow + -1;
var row = tbl.insertRow(lastRow);

if (i == 5)
{
alert("stop");
return;
}

// left cell
var cellLeft = row.insertCell(0);
var textNode = document.createTextNode(iteration);
cellLeft.appendChild(textNode);

// right cell
var cellRight = row.insertCell(1);
var el = document.createElement('input');
el.type = 'checkbox';
el.name = 'txtRow';
el.id = 'txtRow' ;
el.size = 40;
cellRight.appendChild(el);
i++;
}
</script>
<p>
<input type="button" value="+" onclick="addRowToTable();" />
<input type="button" value="-" onclick="removeRowFromTable();" />

</p>
<p>
<span id="spanOutput" style="border: 1px solid #000; padding: 3px;"> </span>
</p>
