OptimizePress Aweber URL Params

Hi,

I’ve set up my aweber form adtraking variable this way:

input type=”hidden” name=”meta_adtracking” value=”[urlparam param=’adtracking’ default=’fallback’ /]”

(removed the > < just to post here)

Then calling my URL http://pesoperfeito.com/teste-url-param/?adtracking=testing

My adtracking field on aweber is being populated with the weird value ’fallback’

Any clues on where I’m messing it?
