<tr style="background-color: rgb(244, 244, 244);" onmouseover="this.style.backgroundColor='#FEFAEB';" onmouseout="this.style.backgroundColor='#f4f4f4';" bgcolor="#f4f4f4">

The reason that works in IE and not Firefox is because you're using JScript syntax, not javascript. Change your syntax to be like
document.forms["form1"].elements[i].name

[jawednazarali]

I suggest always go for standard DOM syntax; and test your Javascript code in Mozilla browsers, I prefere Firefox, because any thing that works in mozilla browser it will work in IE 99% of the time or 100% in my case.

I have never faced any javascript problem, when I followed standard syntax and tested in mozilla browsers.

What about some "blink" codes? Is it works?
