Why doesn't my popup appear in iQueue dropdown?

There are two possible reason for this:

1. Your campaign status is not active (iQueue will display only active campaigns)

2. Your campaign trigger is set to either "Scroll" or "Manual" trigger.  These types of campaigns can not be used in iQueue so if you set your popup to use one of these triggers you will need to change it to "Timed", "Exit" or "Page Close" instead.
