Thread: Changing Variable Within Method

Hello Guys, I am currently trying to generate a table output based upon commission rate. With that in mind I am attempting to alter the "rate" variable given a series of "if statements". Here is my code:

public class table_output{
	public void sales(double salesAmount) {
            DecimalFormat formatter = new DecimalFormat("#,###.00"); 
 
            double Table_cap = salesAmount * 1.5;
            int fixedsalary = 50000;
 
            for(double counter = salesAmount; counter < Table_cap;counter +=5000) {
 
           if (counter < 96000) {
               double rate = 0.00; 
           }
 
           else if(counter >= 96000 && counter <= 120000) {
               double rate = 0.15; 
           }
 
           else {
               double rate = 0.15 * 1.25; 
           }
 
double commissionIncome = counter * rate;
 
//Calculate totalIncome
                double totalIncome = commissionIncome + fixedsalary;
System.out.println(formatter.format(counter))+ " \t " + (formatter.format(totalIncome));
}

However I receive an error to "create local variable 'rate', when trying to formulate double commisionIncome

Please help, and thank you
