Why is my if statement an error?

This code is supposed to stop an object from passing through it, ans if an object hits it, make it so it has to wait 1 second before it can be interacted with again. I thought the best place to but the timer would be after the keylistener, but when I tried to put an if statement down, it just came up as an error, even though it seems to be complete.

What can I do to fix this, and is there a better way to do this?

I put the problem statement towards the middle, and added comment lines at the start and end of the if statement. Thank you for your help.
