Why does it say my funnel is “incomplete”?

In order to track traffic to your funnel, the funnel set up must be “complete” on the funnel builder canvas.

A “complete” funnel consists of at least two pages, with all pages having at least one connection to another page, and each page must have a valid name and URL.

 
Note: Traffic will NOT be tracked for an incomplete funnel as the stats would be meaningless.
