, you have the logical error that the "command substitution" will replace the function with its output to stdout while the (exit) code conveyed by the return command can be retrieved in the $? parameter.

Thanks so much, and just so I understand your quote above. Does this mean that the $zone value I'm returning from the function set_region will just be wiped out everytime?
Also does this look better for the if statement, I'm not sure if || means or, because I'm only looking for those numbers?
Code:
if [$zone eq 4] || [$zone eq 5] || [$zone eq 6] || [$zone eq 7] || [$zone eq 10] || [$zone eq 11] || [$zone eq 20] || [$zone eq 21] || [$zone eq 23] || [$zone eq 25]
then
$zonecheck=1
else
echo "That's not a region\n"
fi

Now it just hangs and throws the same error when you hit enter.
Using comments might be easier for me to explain what I'm trying to do:
#A function to call another function to get a user to enter a valid region in a variable
#Use that variable in another command
#Print out the results from the command
#A function for getting the users region and making sure it's in a valid list
#Request the user input a region and get it in a variable
#A while loop that keep going as long as the user input doesn't match a valid region
#A for loop to test the user input against the valid regions
#Matching with a valid region exit the while loop
#Not matching rerun through the while loop
#Return the zone that was found to be valid
Saying you're getting an error when you hit return without showing us the exact error you are getting wastes all of our time and delays getting help from us. But, in this case it is obvious that you still have the syntax errors in the tests in your if statement, ksh (and any other shell conforming to the standards) requires whitespace separating all of the arguments in a test command (AKA [expression] command), and the numeric equal comparison operator in that expression is -eq; not eq. This might come closer to what you're trying to do, but without seeing how you are calling the functions you're talking about and seeing how you're testing the results produced by this code segment, we don't know whether or not it will do what you need:
This returns 0 even when it does not delete any files.
Is it because -print returns 0?
