Flowify woes

Hello All,
I am struggling with Flowify and was hoping someone might be willing to look at the attached model and tell me what I am doing wrong.
I am getting this error:

“INPUT ERROR: Could not find support group. The support Group must contain three further groups and one of these groups must contain two connection edges.”
FLOWIFY.skp (379.2 KB)

You might look at this video to see if it gives a clue.

Differentiate between terms, different objects > component ≠ group
The error also shows you what to look for.

Well don’t I feel dumb.

Thank you!
