Getting a Note to Display "Correct"

Slide 7, I’m trying to code the notes to show correct when the bounds of the polar curve are entered correctly. I am doing the calculation within the graph for the variables. The conditional statement seems okay,

BUT, the changing the content of the note using WHEN and OTHERWISE don’t seem to be working. I checked some similar things I had tried in the past, but I can’t see what the problem is at the moment.

Thanks in Advance for your wisdom and ideas!

NEVERMIND. I came up with a simpler alternative once I realized what I was doing. But this now works great! Graph feedback until they get it spot on, then a quick visual confirmation and then they move along.
