Javascript question: Looks easy

[Joel Hammer]

Well, I solved this myself. It was kinda obvious.
The command replace doesn't replace the original string. Instead, it returns
a new string. So, instead of just:
string.replace(/.*/,"REPLACED")
it should be:
NewString = string.replace(/.*/,"REPLACED")

Being a newbie at anything just isn't much fun.
