Get rest of var name

[sssssssssss]

Well, what im trying to do is make a temp.var to get the end of a string.

so if the string is bids.sssssssssss.weapons.sword
id want to be able to search through for all bids.sssssssssss
then make a var that contains weapons.sword.
I only want to do this, because there is another var weapons.sword.selleracct.bla bla that I need to pull only a few certain things from on a bid.
