Thank you. You saved me 2 unnecessary pages that I would have to create.
I have at home a MAC with OS Lion and DW CS 6. On my Mac I am able to delete SESSION Variables by clicking on the minus sign in the Binding panels. Also, I am able to set a Session value without any problems. At work I use a Windows 7 Pro with DW CS 6. I was not able to delete a Session variable from the Binding panels. When I try to set a Session value, the following error message appear "You already have a variable named "previousPG". Please enter a unique name." I am sending an image for you to see that I did not have a Session value before I click on the Server Behaviors Panel plus sign -> Webassist -> Cookies -> Set Session Value. Why would this error appear when clearly I there is no php code on the page.
