BlueCube please help this noob out

Hey I am creating an RPG (duhh) and I am having it so you
buy your quests instead of getting them... But I dont know how to do this
I tryed to put it into a shop menu but I only want the player to be able to
buy it once... I then tryed a custom menu but that was WAY too much coading to just find out that it dosnt work...

So if you could hep me then that'd be great....

Oh yeah and I also want the player to be able to speak to someone to
get the information about the quest (or as I am calling them Trials) and
information about what you get from the trial after completion...

One more thing... If posible I would like for the player to be able to go to
any Trial Depo (the building that you go to to get the trials) to receive the rewards... And for each Trial Depo to have differant Trials...

So if you your holyness of RM2k3 could help or any one else then I would greatly apprestiate the help... and once I am done I shalleth put the game Online and post the link up here... Fwanks to you.

Another Fine K!tt3N Rat Production...
