Lesson 20 - building a slider

The code is throwing and error saying that alien.isTouching(germ) is not a function but I am not sure why. The if statement is set up correctly? I tried switching the target and sprite as well and the problem still occurred. Line 29

Very odd and I can not wait to hear what others say. However, I changed alien to joe and it worked fine.
perhaps code studio has a case of the Monday’s


Hello @kayla.armstead.

I believe the error is in line 43 where the alien has been changed from a sprite to the number zero. I believe it should read alien.y (instead of just alien).

Let us know if you still have problems after fixing that!
