In the javascript you have used getElementById() function as

document.getElementById("change")

But the input text element is having only 'name' attribute and no 'id' attribute

<input type="text" name="change" value=0 size="10" style="font-size:12pt;" onkeyup="IsValid('change')">

If the id attribute is not present than getElementById() in IE uses the name attribute hence the scripts work in IE but not in FF

add the 'id' attribute in the text element as,

<input type="text" name="change" id="change" value=0 size="10" style="font-size:12pt;" onkeyup="IsValid('change')">

Do this for all the elements for whom you are using the getElementById() function. This should solve your issue.

Nice! thank you!
I finally stumbled on a post that talked about using the error console in firefox, but all it said was

Error: document.getElementById(text_box) is null
Source File: file:///C:/Users/Nicolas/Desktop/Money%20Calculator/index.html
Line: 23

like 10 times

it works now. thanks a million =D

I downloaded firebug and took a look..I created a few errors in my code intentionally, but it didn't seem to find them. It looks interesting though. I'll read up on it next time I get snagged. Thanks anyways.
