When working on confirmations for forms and events organizations can click on the Advanced Confirmation Setup link to view and edit their confirmation email settings. Sometimes this window won't open.
Check the following:
Sphere will only allow a certain amount of pop-up windows to be open at once. If other Sphere pop-up windows are open, close them and click on the link again.
The fully supported browsers for using Sphere on the back end are Internet Explorer version 7 and version 8 in a PC Operating System (or used through a PC Emulator on a Mac Operating System). If you are using a different browser or operating system that could be why the window isn't opening. Switch to either Internet Explorer 7 or Internet Explorer 8 on a PC system or used through a PC emulator on a Mac system.
