Checking ticker....
actually come to think of it the code you have there doesn't look right to me at all. It looks like the code that links back to their website when you click on the ticker as it has a target in it. The code you what should have a href in it. That refers the link back to the picture of the ticker on their website so that it shows up where ever you place the code. Try doing it again and copying the HTML code. If you can't get it to work on tickerfactory you can click on my ticker and do one there also. It will take you to a different site to make one.
Here is the OH tutorial http://obesityhelp.com/content/howtoaddaticker.html
You go to a site like tickerfactory.com and then you copy (Ctrl C or right click copy) the picture of the ticker (not the html code) directly from tickerfactory and come back to this site and paste (Ctrl V or right click paste) it in the section under User Settings (left side of the screen, above the ads) and it will appear as a signature be sure to click on "enable signature" or if you want it on your profile just cut and paste the picture of the ticker and add it in your profile in any section (My story, Intro, etc.)
