If you gys can see anything that may be causing this problem i would love the help.

Explanation / Answer

The compiler found a symbol that it wasn't expecting or that it thinks is missing. For example, an extra parentheses in any complex block of code, a semicolon placed inappropriately, a semicolon omitted from the previous line, etc. The error is not always on the line mentioned by gcc, but may be on some previous line.
