help with game coding

Hey not sure if this is is the right place but here goes.

A friend an I are using chickenfoot script editor to use while playing an online game (my heroes ability on facebook) but where having trouble with a certain bit of code and wondered of anyone can help.

here's what we need to do, on the sight when u click the fight button it brings up a live fight section with lots of npc's to select, we wondered if its possible to get the code to randomly select one of theses npc's having trouble finding the npc names/ command names not sure what the actual term for it is.

Thanks for anyones help guys
