I have a page which displays a banner ad using the 'PageGroup'
functionality. All works, except when you hit the browser 'refresh'
button (or when a Postback is performed !). Anyway, the line which sets
the PageGroup fails i.e this line :

csContext.TargetingSystem.TargetingContextProfile["PageGroup"].Value =
"Sports";

Thinking I was doing something wrong I tried the example from the
documentation (attached at bottom of this mail) and it too fails for
the same reason on the second click of the button.

I'm totally stuck on this - any ideas are more than welcome.

Regards

Jim

Fixed it !!!!

It seems that the Targeting Conrtext profile was set up such that the
'Page Group' property was a key !!!

I simply created a new key property, took the key dependancy off od
'Page Group' and everything worked.
