Help with Disable Text Selection script

[snoopygirl11]

1) Script Title: Disable Text Selection

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex9/noselect.htm

3) Describe problem:
First, I put in this 'no right click' script-http://www.dynamicdrive.com/dynamicindex9/noright.htm
and it worked fine. Then, I added the disable text selection script, and nothing happened. I tried the disable text selection script on a page without the 'no right click' script, and still nothing happened. I'm using Firefox, but I think it should work with Firefox and IE. PLease help me! (I'm new to this, so please don't don't use too many "big" words ^^')
