This is the paint app I developed using the MIT app inventor platform... when I open this application this runtime error message appears... What should I do?
Rather not after opening, because I can see that I have managed to draw a line. Error appears while drawing?

Thank you so much. Got it solved.

Was able to solve the problem by changing the blocks.
