Problem catching invlaid entry

[Digimstr]

I am having an issue where I am trying to ensure the entry is a valid numerical entry here is what I Have but I am confused if I cause a flag flip how do I reset it when valid entry is inputted so I can leave the loop?

do
{
 cout << "\n\nEnter total count of items being shipped";
 cout << "\n\nEnter the total count here: ";
 if (!(cin >> itemCount));
 {
  //display error message
  flag = 1;
  cout << "\n\nI am sorry but only whole integers are allowed as input.";
  cin.clear();
  system("PAUSE");
  cin.ignore(MAX_READ, '\n');
  system("CLS");
  }//end if
} while (flag == 1);

as always any help is greatly appreciated

Get rid of the semi-colon on line 5, then add an else after the if block where you set flag to 0.
