Please see this forum post:
It will explain what is going on with the flow steps and links. In general the “steps” are addresses that go in a sequence (from left to right) while the links are routes. In your case, the system expect to first “start from” Wall Feeder, then go to Gluing and then to Vertical Feeder and lastly to Horizontal Feeder, in that order. What I’m assuming from the image alone is that you want all the feeders go to the gluing. If this is the case, you can drag and “stack” the steps on top of each other in the first step. This is explained in this tutorial:
I would suggest starting from the very basics first though:
