The code itkamaraj suggested is using the wrong comparison operator, but he just duplicated the code you were using (so if your code was working, the changes he suggested should also work).

Are you saying that the 3rd echo in the suggestion:
Code:
 then echo You have typed pre.

needed to be:
Code:
 then echo You have typed post.

? If so, we would hope that you could correct a typo like that on your own. Please give us some details about your environment and about what is not working. Help us help you.
