aaarrrggghhhhhhh! plea for help

Bloody web page - I tell you what Macromedia might be good for some things but not others. I'm trying to design my own website and found a real nice set of buttons I want to use - only problem is I can't seem to edit them to include my text? Maybe its just me I don't know. I ain't experienced on this at all so maybe i'm just being thick but I've tried everything so if anyone can lend a hand please feel free :)
