Problem with specials box

[RobiD 0]

Can anyone tell me why when I add a special, my content drop down half the page.

If I remove the special, it pops back up to the top.

 

I am using 2.2, STS template and the Simple visitor newsletter with HTML addon.

 

If some one want to see what I'm talking about, the address is: http://safeweightloss4kids.com/catalog/index.php

 

Hope someone can help.

 

Thanks

David
