invalid command name "182718608lcallit" while executing "182718608lcallit" ("after" script) what mean , why isn't collision detection functioning?
okay edit: have different version of same code, know collision detection working score changes, bricks don't disappear , ball doesn't bounce. don't understand why following version has working score while first doesn't, , don't understand why neither of codes delete brick , bounce ball. code has similar error message, different numbers. can please explain, i'm new coding.

your collisiondetect method deletes brick, try things brick later (in if didwehit part of code). make sure wait delete brick until you've done need it!
in tkinter, kind of error occurs if try object has been deleted. tkinter assigns number each tk object creates, funny number in error got. trying execute command named 182718608lcallit, doesn't exist more since deleted corresponding brick.
