Hello, I got an email from one of my networks telling me -

"You're replacing aff_Id with your vaiables. This is messing up our tracking and will potentially not track your conversions either. You cannot replace aff_id

Something is happening where your aff_id is being replaced by a new variable from P202 on every click."

Any ideas?

I am using a link like this I got from them for the offer in P202

http://www.network.com/aff_c?offer_id=89&aff_id=96&aff_sub=

Anybody?

Prosper can only add variables to the end of the url, it's not possible that it is rewriting a variable in the middle of your url. There must be something else going on.
