*I dont understand what this error means, if references it also every time i start the line with "if" after line 199, if anyone could explain to me It would be a huge help, Thanks!

219 C:\Users\Gaming-PC\Desktop\C++ Files\Tic-Tac-Toe.cpp expected ,' or;' before "if" (This is exactly what the error reads)

You have ab extra } on line 197. get rid of that and it should compile. No sure if your code is exactly right though. it looks weird that you have 3 if(!found) statements.
