contents of variable in form

[MaxDax]

Hi

How do I get the contents of a variable into a hidden input field?

ie:
<input type="hidden" name="abc" value="xyz">

If I have a variable name foo with a value of 123. How do I get the contents of foo (123) into the hidden field named "abc"?

I have tried -
<input type="hidden" name="abc" value="<script type="text/javascript"> document.write("foo");</script>">
but that just writes the contents of foo to the screen.

Any clues would be most appreciated ...

Thanks
MaxDax

<script type="text/javascript">
var foo = 123;
document.write("<input type='hidden' name='abc' value='"+foo+"'>");
</script>
