Problem with arithmetic operand, used to work but now it doesn't.
Hi. I'm having a problem with two lines of code. In my first program, those two lines compiled with no problem. Now, as I redid the program to do arrays, now those two lines are giving me problems and I have not changed them. Here is my code with compile details. The offending lines are in main(), when I'm trying to multiply sale_comm.

Script started, file is output.out
