string not a type.

I'm getting this error and can't figure out why. I know this i am an ultra
n00b and it's probably a really simple answer but I've tried. I have included
<string> and using std namespace.

#include <cstdlib>
#include <iostream>
#include <string>
#include <sstream>

using namespace std;

int main(int argc, char *argv[])
{

    int iOption;
    int iEmployeeID;

    struct Employee_data {
            string sName;
            int iID;
            float fSalary;
            string sDOB;
            string sDOH;
            }

    cout << "Welcome to employee database. Please choose from following options." << endl
         << endl;

    cout << "1. List employee information." << endl
         << "2. Add employee information." << endl
         << "3. Delete employee information." << endl
         << "4. Edit employee information." << endl
         << "5. Save changes and exit." << endl
         << endl << "Selection: ";

    cin >> iOption;

    switch(iOption) {
           case 1: 
                {

                      cout << endl <<"You chose option 1, please enter ID# of Employee you would like to review." << endl
                      << "Selection: ";
                      cin >> iEmployeeID;

                  break;    
                }
           case 2: 
                {
                      cout << "You chose option 2, please enter ID# of Employee you would like to add." << endl
                      << endl << "ID#: ";
                      getline (cin,Employee_data.iID);

                  break;    
                }
           case 3: 
                {
                      cout << "You chose option 3, please enter ID# of Employee you would like to delete." << endl
                      << endl << "ID#: ";
                      cin >> iEmployeeID;
                  break;    
                }
           case 4: 
                {
                      cout << "You chose option 4, please enter ID# of Employee you would like to edit." << endl
                      << endl << "ID#: ";
                      cin >> iEmployeeID;
                  break;    
                }

    // 1 list employee information. employee information includes. name, date of hire, date of birth
    // salary, employee id number.

    // delete employee information.

    // add employee information, take in name, date of hire, date of birth, salary, employee id number
    // store for later retrieval

    system("PAUSE");
    return EXIT_SUCCESS;
}
}

Sorry I think I found the mistake. I was trying to getline on an int value...
i've changed that but now am receiving. "expected primary expression before
'.'" along with a build error. I'm not sure what that means.
