I am doing a assignment for my mid term, and I make it with reference to this video:
App Inventor Tic Tac Toe Tutorial: More Procedures, For Loops, and Lists
When I try this app, it shows this information:
- error message: the operation + cannot accept the arguments: , [“X”], [1]
And I looked the video comments below, someone says: change the value of global turn from O to X.
But I don’t know how to do it, please someone help me, thanks!!

connect to Comanion, right mouse clock: “Do it”:
So “Do it” mean test result?
