Can't Change my Signature

[Terri]

I recently decided to put up a sig, so I did, and it worked. Except the image did not show up because of an HTML error.

Anyways, I went back to edit the HTML, and now I cannot do anything. I type whatever I need to in the box, but when I click save or preview, absolutely nothing happens.

Does anybody know whats up? I gave it a few minutes, changed browers, logged out but nothing seems to give.

Any help would be appreciated

Thanks
