In the note component on screen 1, you can change it so that the only line above the content sink is correct = when graph111.number("I_3")=1 or graph111.number("I_5")=1 or graph111.number("I_7")=1 "Correct" otherwise "Not there yet, keep working"
I found the values of I_3, I_5, and I_7 by playing with the calculator.
