[Evil-Magus]

I am making some levels to get added to G2K1(my chances are slim) and im making a shop, the shop will sell bread, pie, and maybe some insturments and hats! I have most of the scripts but I need the script that makes it so if the player says "buy bread" s/he will get bread, if he says "buy pie" s/he will get pie, and so on, but so far I have:
if (playersays(buy bread)) {;}
if (playersays(buy pie)) {;}

Please help, and I know this probably wont get put online, but its fun to make!
I also need it so when I put up the hat and Insturment GFX it wont show it in all of the different posistions...
