C++ declaration error

Hello (C++) programmers of southperry. I'm having a really simple problem with this code that I can't figure out.

Code:

int main()
{
srand(time(NULL));
int upperBound = 100;
int lowerBound = 1;
int range = upperBound - lowerBound;
int guess = 1 + rand() % range;
char playersRespond;
cin >> playersRespond;

do {
    if (playersRespond == '1') {
      //do something;
    } else if (playersRespond == '2') {
      //do something;
    } else {
    cout << "Please type in 1, 2 or 3" << endl;
    }
  } while (playersRespond != 3);

char c;
cin >> c;
return 0;
}

My compiler says I have a "declaration error" at the line:

} while (playersRespond != 3);

I have no idea what I'm doing wrong.

edit: does it have something to do with me saying "while (playersRespond != 3)" when i already have an "else" statement within the "do"?
