Multiple Text Entry - Correct answer not triggering

Hi All, 

This is the first time I've attempted to create a multiple text entry slide using the "Pick 1" method, and I'm having some issues I can't seem to figure out. I've read just about every discussion on this topic I could find, but so far no luck.

The main issue is that I can't seem to get the correct answer to trigger. I'm sure it has something to do with how the variables are set up, but I can't figure it out. I also need the learner to be able to try again if they answer incorrectly, but not sure if I need some sort of "clear" variable to make that happen. Any help is greatly appreciated!
