I'm new to JavaScript and even to website coding. I'm trying to populate a form dynamically and am having trouble with FF7.

To start I couldn't even pass the name of the form as an argument with FF7. After simplifying the code to see what's basically wrong I have come to something funny.

In the code below at least the input element gets initiated, but if I just declare a variable then it doesn't!

With IE8 and even IE6 all my original code worked perfect. I could populate the whole form and then change it dynamically.

What am I doing that FF doesn't get?

Thank you.

Rick Trelles
