Shell Programming and Scripting

im suppose to write a script that examine how many users are logged in the student server. if there are less than 10 logged in a message suppose to display that says "there are less than 10 users currently signed on" and if there are more than 10 logged in a message suppose to display that says "There are currently ### users signed on the server" the ### is the number of users logged in

this is what i have so far

clear
user= 'who | wc -l'
if [ "$user" -lt 10 ]
then
echo "There are less than 10 users currently signed on"
fi
if [ "$user" -gt 10 ]
then
echo "There are currently \c users signed on the server"
fi


can someone give me an idea on how to fix this????
