Remember that you can not call a javascript function from PHP. You can only put Javascript code that is executed when the page (PHP result) is loaded. Normally, I put this kind of code, in a funcion called in the "onLoad" event of the page; to assure the page is loaded, and the form is correctly displayed. I suposse your code may be actually working, but just before the form be active. And as my personal prefered choice, you can replace your javascript code, for a simple line on your form: <input type='text' name='int_amount' <?php if ( ($this_user != $my_user)||($this_pass != $my_pass) ) echo " READONLY"; ?>> -- José Miguel Santibáñez jms@xxxxxxxxx
