The file DebugFour4.cs has syntax and/or logical errors. Determine the problem(s), and fix the program.

my code

using System;

using static System.Console;

class DebugFour4

{

static void Main()

{

double sales, commission;

string inputString;

const int LOWSALES = 1000;

const int MEDSALES = 5000;

const int HIGHSALES = 10000;

const double LOWPCT = 0.05;

const double MEDPCT = 0.07;

const int BONUS1 = 1000;

const int BONUS2 = 1500;

WriteLine("What was the sales amount? ");

inputString = ReadLine();

//changed inputtString to inputString

sales = Convert.ToDouble(inputString);

commission = LOWPCT * sales;

if (sales > LOWSALES && sales <= MEDSALES)

{

commission = LOWPCT * 1000;

commission += (sales - LOWSALES) * MEDPCT;

}

else if (sales > MEDSALES && sales <= HIGHSALES)

{

commission = LOWPCT * 1000;

commission += (sales - LOWSALES) * MEDPCT;

commission += BONUS1;

}

else if (sales > HIGHSALES)

{

commission = LOWPCT * 1000;

commission += (sales - LOWSALES) * MEDPCT;

commission += BONUS2;

}

WriteLine("Sales: {0} Commission: {1}", sales.ToString("C"), commission.ToString("C"));

}

}

only 87% correct

output needs to be What was the sales amount? Sales: 43,987.00 Commission: 5,559.09
