Bash script and getopts outputting saved variables - bash

Question

I'm trying to put together a script to monitor files and im having a hard tiem with getopts. If I run more than once the shell values dont changes... There's a ton of clean up but I've been stuck on this one issue for a couple hours so ...
#!/bin/bash
function printUsage {
echo "Usage: $0 [-e environment] [-r region] [-l logtype]"
echo "Requirements:"
echo " -e environment to look in; prod or dev"
echo " -r 3 digit region designation"
echo " -l log type to find; soap, message, main, service, or detail"
echo " example: $0 -e dev -r 111 -f soap"
exit 0
}
if [ $# -lt 1 ]; then
printUsage
fi
while getopts "e:r:l:" opt; do
case $opt in
e)
environment="$OPTARG"
;;
r)
region="$OPTARG"
;;
l)
logtype="$OPTARG"
;;
\?)
echo "Invalid option: -$OPTARG"
printUsage;;
:)
echo "-$OPTARG requires an argument"
printUsage;;
esac
