[Javascript] Loop problem

[Chris Tifer]

 From the looks of it, this would never loop:

> for (i=1;i=<%=Numfrm%>;i++)

Should their be some of of comparison, such as:

<  or <= or > or >= or ==

When you say " var1 = var2", you're automatically setting
var1 to var2's values. == checks for equality.  That'd be where
I started to debug.
