So are you going to tell us which lines are the ones indicated or are we supposed to guess?

put your code in code tags next time.
If you see "cannot find symbol" errors, most of the time, its due to variable declaration problems. In that case, try declaring the variable.

Excellent post. Thanks!

Thank you so much! That fixed my problem with the variable declarations, but now it says that the variable INPUT might not have been initialized at the "while" part of the "do" statement. Is this an easy fix as well? Thanks
