Jack has written a program that computes and prints the average of $10$ test scores. The program prompts the user for each input score. Here is the code for this program:

count $=1$

while count $<10$:

score $=$ int$($input$("$Enter test score number $"+$ str$($count$)+"$: $")$

total $=$ total $+$ score

count $=$ count $+1$

average $=$ total $/$ count

print$("$The average test score is$",$ average$)$

This program contains an error. Determine what type of error this is$,$ describe how it is detected, and correct it$.$
