Data If statement (yes or no)

I have the program:

#!/bin/ksh
echo Please enter yes or no
read n
typeset -l n
if [[ $n = yes ]]
then
echo My name
exit
else
echo delete my name
fi

Question:

How can I make the program accept only the word "yes" or "no" otherwise it will ask the user to re-enter?

Thanks!

Code:
#!/bin/ksh
echo "Please enter yes or no"
read n
yes=$(echo $n | tr -s '[:upper:]' '[:lower:]')
if [[  "$n" = "yes"  ]] ; then
  echo "My name"
else
  echo "delete my name"
fi
exit

THis will not work....if user enter data other than "yes" or "no"....the user must be asked to re-enter the data UNTIL "yes" or "no" is entered!!!!

I did not test it and thus it is too long. Check it out and you will have a good go

Can you post the modifications then. It might be that someone else likes to take a look at your code and solve a problem this way ;-)
