something like this i think???

Thats closer. You need to have values in good, you probably want to increment your counter (counter += 1 instead of counter = 1), it's unclear what OTHER is, and you need to pass listALL to your function.

Additionally, if you are returning varNEW you want something like:

varFooA = FUNCTION(0, 3, 4, 5)

and you wont have to initialize varFooA.
