Why isn't the length (or maybe Find?) function for my map not working?

I have a map (photo 1, named “Prefered Players To Attack”), which in debug mode it is just as it is supposed to be (photo 2), but for some reason when I go into debug mode (photo 3/4) the length given by the function isn’t 2, and the Find function can’t work properly, how do I fix this?
(Btw what I’m trying to do here, is to just take a random value from the map)

Thanks for the help in advance!

I just discovered that I’m stupid and the reason both the Find and Length function didn’t work, was just because in the debug mode I wasn’t in the node that actually calls both of them, so yeah, everything works perfectly now!
