Percentage verses Fixed Rate

Hello,

Got a quick question…

I am setting up my system to support payouts for affiliates.

What I need is a place to enter a %Percentage for each sale

that is made within the site… Though what I found is a place to

set a fixed rate…

My question is, Is there a work around for this… I really need to use Percentages %

Another issue is, I have 3 paid packages total in the ProSites Plugin and the Affiliate plugin, to the best of my knowledge only supports one package.

Having a way to set pay to a percentage would drastically take care of this issue.

Thanks for your help

Right now I am using ProSites and the Affiliate Plugin
