Getting if statement to stop running when satisfied

I cannot get this if statement to stop running when the beam is broken. I tried to by changing a variable within the if statement to stop it from running but the variable doesn't seam to change.

This is Arduino code isn't it?

BTW could you just remove all the comments as they describe exactly what the code does, therefore are completely redundant. Consequently they prevent you from posting the code and use syntax highlighting.
