Hi cubist,
I am assuming that you are referring to the email notification sent to the administrator (or the address in the To Field). I set up your scenario and it appears that this might be a bit of a bug. But there is a work-around.
Create a Text Field (EmailToSend) for the Admin Email address to be filled when conditions are correct.
In the Email Field Setup, use the To(Fields) and add the EmailToSend field.
On the EmailToSend field, set up a condintional when Route =true like:
States: is Filled
Value: AdminAddress@email.com
So, when your conditions become true, the Admin Address is entered into the EmailToSend field.
Hope that helps,
Randy
