Im trying to understand how to do something I'm working on at work

I'm trying to read a users name from input store it in name, then enter a while loop as long as name is not equal to x, then if name is equal to name do nothing, but if name is != name do something, exit if statement, check name variable if not x continue looping, if x end program. Does that make sense?

---------- Post updated at 09:50 PM ---------- Previous update was at 09:35 PM ----------

so now code is
Code:
#!/bin/ksh
x="x"
echo "Enter a name: "
read NAME
while [ "$NAME" != "$x" ]
do
echo $NAME
echo
if [ $NAME == $NAME ]
then
echo ":"
else
echo $NAME
fi
echo
echo "Enter a Name: "
read NAME
done

When I view the output it keeps asking for a name, and is ignoring the x if name is x, and looks like it is infinite looping. Why?
