Illegal else without matching if?

[JoeyMan86]

I'm doing a project for school that calculates tax rates. I just started and I wanted to test it out. I never had this problem with "else if" statements before. I used "else if" before and it only gave me this error this time. I did a bit of research and I still don't understand what is going on. Thanks in advanced!

  #include <iostream>
#include <iomanip>
#define _USE_MATH_DEFINES	
#include <math.h>

using namespace std;

int main()
{
	int GrossIncome, NetIncome, TaxBracket2Remainder; 
	double AmountofTax;
	const int TaxBracket1Total = 31000 * .2580; 
	const int DifferenceBetweenBracket1and2 = 45282 - 31000;

	cout << "Hello!\nToday, this program shall calculate your net income using your gross income.\nAlso, if your gross income has cents in it, please round." << endl;
	cout << "Please input your Gross income: " << endl;
	cin >> GrossIncome;
	cout << endl << endl;

	if ((GrossIncome > 0) && (GrossIncome <= 31000));
	{
		AmountofTax = GrossIncome * .2580;
		NetIncome = GrossIncome - AmountofTax;
		cout << setprecision(2) << fixed << NetIncome << " is your net income if your gross income is " << GrossIncome << endl;
	}

	else if (GrossIncome > 31000)
	{
		TaxBracket2Remainder = GrossIncome - DifferenceBetweenBracket1and2;
		AmountofTax = TaxBracket1Total + (TaxBracket2Remainder * .2775);
		NetIncome = GrossIncome - AmountofTax;
		cout << setprecision(2) << fixed << NetIncome << " is your net income if your gross income is " << GrossIncome << endl;
	}
	return 0;
}//end main

You have a semicolon on line 20 that should not be there

Silly me. How could I be so stupid!
