I have tried to use some codes for a scrolling marque but they will not work with my Bravenet site!!Help....and don't use big terms to explain please.

On which page did you enter the code? There is no trace of it on your main page. Or did you think you could use another editor and then go back to Wizard and Publish?

Do you mean that
1. you saw nothing or
2. that it didn't scroll?

1. just means that you made a mistake somewhere
2. would be because marquee isn't an official html tag and doesn't work when viewed with some browsers.
