FL does not exist in current context

Question

I am having a problem with my code. I have defined "state" as a global variable and the user needs to input one of 3 states. Based on the state chosen, I need to select a tax rate. I wrote an if statement to select the tax rate but, until the user
inputs the state, the variable isn't in the code. I am new at coding.

namespace CIS115Wk7ILab
    class Program
        //Global variables
        static String custName;
        static String state;
        static Double totalSales = 0, totalCost = 0, taxAmt = 0, itemPrice = 0;
        static int itemsPurc = 0;
        static void Main(string[] args)

            //Student Name: Frances J. Atwood
            //Date: 04/19/2015
            //Professor: Debbi McCloud
                Console.WriteLine("Welcome to Atwood's Dry Goods Store");
                readInput();
                computeTotal();
                computeTax();
                Console.ReadLine();
            public static void readInput()
                Console.WriteLine("Please Enter the customer name");
                custName = (Console.ReadLine());
                Console.WriteLine("Please enter the State where your purchase is being made. Florida/New Jersey/New York");
                state = (Console.ReadLine());
                Console.WriteLine("Enter Item Price. Enter -1 to quit");
                itemPrice = Convert.ToDouble(Console.ReadLine());            
            public static double computeTotal()
               do
                   totalCost = totalCost + itemPrice;
                   itemsPurc++;
               while (itemPrice!=-1);
               return (totalCost);
            public static double computeTax()
                double taxRate = 0;
                if (state == FL)
                    taxRate = .06;
                else if (state == NJ)
                    taxRate = .07;
                else
                    taxRate=.04;
                taxAmt = (totalCost*taxRate);

@fjatwood,
As you defined state is a static String. But just FL is not a string. You should assign string to state.
So add double quotes to FL.
And the same as "NJ".
