Correct an error in my strategy

Good evening. Would have to give a little more code to understand. I'd say non-compatible variable types

based on the sym i'm assuming its a symbol . So a string

You are sending a different type of a variable into another type of parameter in a function.

like this :

int OnInit()
  {
//---
  symbol sym;
  check_orders(sym,10);
//---
   return(INIT_SUCCEEDED);
  }
class symbol{
string name;
};
void check_orders(string sym,int swipes_to_do){

}

Why make people guess.  If you want help post the code with the error line highlighted
