Thread: Spot the syntax error

I can not, for the life of me, find the syntax error. My compiler says it occurs at "void show(PRODUCTS rec);" before "rec". Also, can anyone tell me why my report function does not work correctly?

Code:

Wow, I feel stupid. Not only is the error gone, but my report function is also working properly now. Thank you very much for your help.
