Encrypt Email script won't validate

1) Script Title: Encrypt Email script

2) Script URL (on DD): http://www.dynamicdrive.com/emailriddler/

3) Describe problem: this script wouldn't validate on http://validator.w3.org

I made the following changes (in red), and now it will. (NOTE: script works as is, just won't validate, so if this is not posted in the correct spot, I apologize.)

THIS IS MY PERSONAL EMAIL ENCRYPTED

The reason I made the changes I did was because that is what it said to do in the help section of the validator. The script still works. (No, I know nothing about Javascript.)
