Do while loop not executing properly

[Planet Telex]

My do-while does not execute properly and I'm not sure why. I believe it has something to do with my if...else if statement because the loop executes properly if I isolate either of the if statements. Any help would be greatly appreciated.

  int option;
	bool valid;

        cout << "Enter an option ((0-6) - 0 to exit) ";

        do
	{
		cin >> option;
		valid = true;
		if(!(cin >> option))
		{
			cout << "\nInvalid entry. Enter an integer (0-6) ";
			cin.clear();
			cin.ignore(numeric_limits<streamsize>::max(), '\n');
			valid = false;
		}
		else if((option < 0) || (option > 6))
		{
			cout << option << " is an invalid entry. "
					          "Enter an integer (0-6) ";
			valid = false;
		}
	}while(!valid);

You're reading the value twice.

Reading the value twice? What do you mean?

You read into 'option' on lines 8 and 10. You probably want to change the condition in the if statement on line 10.
