Trying to make a loop and repeat a question.

Question

Hello all,
I am trying to get a question to repeat itself only if the user enters an invalid amount. I have got the program to generate the invalid question "This is an invalid rate of pay, please enter a valid rate of pay.", but after the program produces this question, the program will still continue (ask the next question) as if the input was valid. I have tried several different if and while statements to try to manipulate the program to call the previous question, but it will not????? Thank you all in advance.I am at a loss. Can someone help please???? Here is the section of code:
// Employee's hourly rate.
System.out.print( "Enter hourly rate of employee:" );
Double employeeHourlyRate = input.nextDouble();
System.out.println();
// Monitors pay rate for validity.
if ( employeeHourlyRate <= 0 ){
System.out.println ( "This is an invalid rate of pay, please enter a valid rate of pay." );
//Loops back to hourly rate question.
I THINK THIS IS WHERE I NEED A LOOP COMMAND.?.?               
} // Ends loop program.

Hello and thanks for the advice! I have reconstructed as you suggested. However I am receiving 3 errors. I would also like the program to just repeat the question "Enter hourly rate of employee:". Here are the errors. How do I make this work? Thanks for the help. If it makes a difference I am running windows XP and using text pad.
1. Payroll1.java:34: cannot find symbol
symbol : variable employeeHourlyRate
location: class Payroll1
while( employeeHourlyRate <= 0) {
2. Payroll1.java:75: cannot find symbol
symbol : variable employeeHourlyRate
location: class Payroll1
else { grossPay = employeeHourlyRate * employeeHoursWorked;
3. Payroll1.java:82: cannot find symbol
symbol : variable employeeHourlyRate
location: class Payroll1
System.out.printf( "\nHourly rate: $%.2f", employeeHourlyRate );
