    I have tried may ways and it just starts at 0 then adds 1 and stays at one no matter how many cells are there what am I doing wrong?

    <html>
<head>
<script type="text/javascript">
function insCell() {
	var apples = 0
	if (apples<5) {
  	  apples ++
	  var x=document.getElementById('tr1').insertCell(0)
	  x.innerHTML="John"
	  alert("Apples value: " + apples)
	}
}
</script>
</head>
<body>

<table border="1">
<tr id="tr1">
<td>Peter</td>
</tr>
</table>
<br />
<input type="button" onclick="insCell()" value="Insert cell">

</body>
</html>
    Code (markup):

    You're setting apples=0 inside the function - you need to move it outside.

    Glad you figured it out. Coincidentally I changed my signature yesterday so that it doesn't contain a link - though I don't know why that would stop my replies showing on the forum display. If it keeps on happening I'll get in touch with DigitalPoint.
