If you run a test on a variable that may be empty, quote it. Often you 
see a character appended to the variable and the variable being tested 
against that, but I've never found that to be necessary

if [ "$interval" == "" ]
then
	interval=300; # five minutes default setting
	echo "interval blank"

elif [ $interval -lt 200 ]
then
	interval=200; # 3 min 20 minimum setting
	echo "interval increased to minimum 200 seconds"
fi

should work
