Logic error?

[Duki]

This program works unless I input 's' for marital status. Does anyone see my logic error?

#include <iostream>
#include <iomanip>

    taxPay = taxAmount ( numChild , grossSalary , penPay , maritalStat ) ;

    cout << fixed << showpoint << setprecision(2) ;
    if ( taxPay < 0 )
    {
        cout << "Tax Owed:  $0.00" << endl ;
    }
    else
        cout << "Tax Owed:  $" << taxPay << endl ;

}

You've been here long enough to know that a question like that is worthless here! What the **** does it do wrong? Other than asking for "Marital Satus" ;)

Hm... well it's supposed to determine the taxes due according to certain circumstances. does that help?

i put in single, 14999, and .01 into pention and should get $1252.35 due, but instead i get 1402.35

Ok, nevermind. I got it working, it was actually always working. It was just a human calculation error on my behalf. Thanks.
