Hi Toby
I altered your code to take into account what you just posted, so it looks
like this now:
<script type="text/javascript">
function sum ()
{
//var A = document.getElementById('a');
var A = parseInt(document.getElementById('a'));
//var B = document.getElementById('b');
var B = parseInt(document.getElementById('b'));
//var C = document.getElementById('c');
var C = parseInt(document.getElementById('c'));
C.value = A.value + B.value;
}
</script>
</HEAD>
<BODY>
<div>
<input id="a"> +
<input id="b">
<input type="button" onclick="sum();" value="=">
<input id="c">
</div>
When you click the button now nothing happens - no value for C appears on
the screen!
Any obvious mistake in my interpretation of your last post please?
bye
David
