Hi,
this is the second time i've attempted posting to the forum... the first time it deleted the message I wrote so i'm keeping this one brief
.
I am attempting to pass objects using sessions but I keep recieving the following error: "Call to a member function on a non-object". I can create the policy object, but I can't call any of it's functions...
Can anyone else see where I am going wrong?
Cheers,
Priar
