I remade the code and cut it down so it would be less memory intense by replacing some style codes with a main style sheet and also used css to control the spacing of the line numbers to decrease the number of  's that were necessary. The ones in the sourcecode still remain. Also, when there was a linewrap this would produce errors so I imposed a no linewrapping property in the style. However, this ONLY works in FIREFOX. For whatever reason Internet Explorer chooses to mess up the css as it sees fit.[PHP]<html>
