First thing's first. I think getLine is supposed to be getline (unless you have a function of your own defined or is a Windows API call). Second it is because your functions are declared with (string OP, int value) on both and you are only pass "get" to both. You have to pass ("get", 8) where eight is some number. Try that first and see if it helps.

The Errors in question:
1
2
 
save << User.Gold("get") << endl;
save << User.Level("get") << endl;

Your declarations of them:
1
2
 
int Gold(string OP, int value);
int Level(string OP, int value);

Both those solutions didn't help, the results are still the same.

Here is how to use getline() => http://www.cplusplus.com/reference/string/string/getline/

Here is the code fixed, I moved a few things around and commented out the getline. Had to include the system header to keep errors to a minimum.
