Problem with calculating number entered to display prompts

What I'm having issues with is when I prompt a user to enter a number of test scores, if they enter a number greater 1 the Enter Score prompt is suppose to display the number of times they requested.

So if they enter a 4 "Enter Score:" is to display a total of 4 times. What is happening at this point is no matter how many numbers I put in only 1 displays and the prompt to enter test scores appears again and goes through the loop.

Test Score Application

Enter the number of test scores to be entered or a zero to exit -> 5

Enter score: 45

SUMMARY
Score count: 1
Score total: 45
Average score: 45.0

Enter the number of test scores to be entered or a zero to exit -> 5

Enter score: 102
Invalid entry, not counted

SUMMARY
Score count: 1
Score total: 45
Average score: 45.0

Enter the number of test scores to be entered or a zero to exit -> 0


Test score program terminated by the User.


What is suppose to happen is when a 5 is entered they are prompted again 5 times to enter test scores but right now that's not happening. Also if they enter a number greater than 100 they are to be notified and then prompted again however the loop is just starting over again instead. Very confused. I'm sure it's something simple that I'm missing. I hope my question made sense.
