Before writing my question, I would like to point out that I have read the FAQ beforehand - I'm just too dumb to understand what to change - sorry !! By default the 5 coop ads on my site are displayed vertically - I have worked out that to change this to horizontal format I need to edit this line - ("include_path") . ':../:../../:../../../:../../../../'); the question is, how ?
Its got nothing to do with that line at all. I'm assuming you are using the latest version. Go to to the setup instructions page. Change the AdType to whatever you require (often Only Text Link). Change Ads To Display to the number you want displayed. Finally change Separate Ads With from the default <br /> (line break) to whatever you want to be displayed (e.g. -, [space],). If you want more control you can always separate with </li><li> and then use CSS for the formating (obviously starting the first list item and ending the last list item around the $CoopAds output. HTH
