How to add backup ads on google adsense??

[high_plains_drifter]

I want to show ads from my smowtion account to fill up my inventory but cant figure out how to do it

in the option screen of 'create a new ad' on google adsense there is an option for 'Backup ads' whixh you can select 'show other ads from another URL'

but in my smowtion account i get a code like adsense, not just a url


So how do i do this???
