Need help with Functions

stc5097 (9)
the project i am creating is for a small theater. the program allows a user to input the row and seat they would like to buy. i created a function that asks the user for the row and seat and then it is suppose to change the value of the spot in an array from # to a *. when i display the seating chart after they input a seat, the value is still a # and im not sure why. below is my code. could really use the help. please and thank you
