Hello everyone:

I have this problem:
I need to check progamatically a Checkbox named 'comp' only when an input text field named 'cant' receives something.
Here is my code, it is not working at all.

$stream .= "<td><input type='text' name='cant' id='cant' size='5' onChange='document.form1.comp.checked=true' /></td>";
$stream .= "<td><input type='checkbox' name='comp' value=$i /></td>";

this code is within a form named 'form1'

Any help is welcome.
Thanks in advance.
