#include <iostream>
#include <string>

using namespace std;
int main()
{
int optionvalue = 0; string option;
cout << "welcome to the simple text game!";
do
{
cout << "\n\nplease select one of the following options:" << endl;
cout << " 1: play \n";
cout << " 2: help \n";
cout << " 3: option \n";
cout << " 4: quit \n";
cin >> option; optionvalue = atoi( option.c_str() );
//atoi() converts a char * to an int. returns 0 if input is not an int.

if (optionvalue == 0)
cout << "error: you did not enter an integer value?! please try again!"<< endl;

else if( optionvalue < 1 || optionvalue > 4 )
cout << "error: invalid option selected! please select from 1,2,3 or 4" << endl;

you need a } after the return 0;

You should really use the [code] tag and also when coding indent all your code so you can find these errors easily.
