By looking at the code on your site you have a malformed html tag in the code.
<align = middle
This appears just before the google script. Firefox will ignore this. IE won't. Check your google code. It appears you may have tried to modify the google code to center it but did not do it correctly.
Also, The ads section in Dolphin was designed for selling ads on your site. The built in banner system will add code to count the number of clicks on the banners your selling space for. These spots were not meant for script. Only for HTML.
To insert google adsense code it is best you modify the template instead. Look for the _footer.htm template file in templates\tmpl_uni and place your adsense code before or after the existing banner tag.
I don't recommend using dolphins built in banner system for adsense or anything else requiring javascript.
