Using correct with feedback (evaluating function)

I would like to allow for multiple correct explicit equations and show feedback on the slide of correct or try again. I am working on the explicit equation on slide 4 and getting an error in the note about an undefined correct variable.

Thank you for your help!

You didn’t define correct as a variable in the explicit2 CL, you just used the sink. So change that line to:

correct = (C1 = U1) and (C2 = U2) and (C3 = U3)
correct: correct

and then in the other component, refer to it using explicit2.script.correct

You are amazing–thank you!!
