Function Returns
I'm having a little trouble returning a value from a function or calling it, I'm not quite sure.

I'm calling the function here
Code:
function region_lookup_with_details {
        results = $(set_region)
        echo $results
}

This is the function I'm calling
Code:
function set_region {
        zonecheck eq 0
        while $zonecheck eq 0
        do
                echo "Please enter the region you want to use\n"
                read zone
                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 eq 1
                else
                        echo "That's not a region\n"
                fi
        done
        return $zone
}

This is the error I'm getting
Code:
./test[150]: region_lookup_with_details[57]:set_region[15]:2: not found [No such file or directory]
