the missing () was the trick!
However, I'm passing in a few variables, so I can't just take it
out-though every single function would be passing the same variables.
so something.func() is actually
something.func(string, list)
How would I modify it to include them? Sorry I didn't include them the
first time, I was trying to simplify it to make it easier...oops!
