Im trying to get this Raptor program to:

$*$Allow user to input a set of names and grades and store them in seperate arrays.

$*$Validate that the grade entered is an integer from $0-100,$ and prompt user to correct entry.

$*$Calulate the average grade, lowest grade, highest grade, $60$ and above passes, below $60$ fails and out info in a message.

Ive got it working up to calculating the sum. I dont want the user to have to enter anymore input. I really just need help figuring out a condition that will get me out of this loop so I can continue finishing the program. Please follow along through the flow chart tho fully understand my approach to accomplishing this.
