while loop problems

I have a problem validating my script. The start of my script begins like this:

Quote:

while yesno=[Yy][Ee][Ss]

do

then after this i have all of my script and functions.

at the end i close the loop with this code:

Quote:

echo "Would you like to run the HITS search again?: "
read yesno

done

What i want to know is, how do i make the loop so that only Yes or no can be an answer?

and if the wrong thing is entered how do i get an error message to appear?
