'no comments whatsoever' is never fun when you are digging through someone else's code. Do these multiple forms actually point to different actions? I am just trying to, like you, wrap my head around this...

Perhaps, if you want to post some form of the code, maybe I can help understand? (as much as possible on a friday evening anyway...)

Edit - just re-read in the OP that they do have different actions...still, if you respond before I head out for the night perhaps I can help...
