How do you get rid of the top banner that says "User Lookup"? I have already tried replacing it but it stangely didn't seem to work. Help would be much aprecciated.

You mean where it says "User Lookup: whatever"

If you mean that then use this code

<style>center font b{display:none}</style>

If you mean the actual banner then use this

<style>table{background:none}</style>
