[sssssssssss]

I think the first part of what you did will help.

Basically the var is
category_accountname_itemname={itemimg,itemprice,i temposteddate,itemexpiresdate}

so something like:
weapons_sssssssssss_sword={sword2.png,10,06042010, 06052010}

but in the gui, they select a category first, then it pops up:
item name item image seller(accountname) end date

just dont know how to search the dbnpc to first pull up category, then post the stuff right above here according to each category selected.
