While Loop assistance.

I am trying to make a simple while loop which reads in a text until the person types quit. And it's not working, and I know it's a rather simple problem I just can't seem to understand... Once again all assistance is greatly appreciated.

#!/bin/sh
astring="z"
while astring!="quit"
do
read astring
if astring="z"
then
astring="hello my name is Gsmith and I have 5 dollars"
echo $astring
else
echo "Never again"
fi
done

Tools perhaps the issue was with variable names

try the following:

#!/bin/sh
astring="z"
while [ $astring != "quit" ]
do
read astring
if [ $astring = "z" ]
then
bstring="hello my name is Gsmith and I have 5 dollars"
echo $bstring
else
echo "Never again"
fi
done

Once again you've saved my day!

yes that was in fact the problem... odd how that worked. I will have to mind my variables much closer.
