Flow is not accepted by origin or destination.

What i want to create is the following: There is a download button on the Overview page that contains a dataview (with this Microflow). This download button activates this microflow which retrieves the documents related to the selected item. Than it counts the amount of items on that list and stores it in a variable. In the loop another variable is created that keeps track of the amount of downloads The document is downloaded. At the the end the countdownload gets a "+1" The split checks if the first count and the countdownload variable are equal. If not donwload next (false line (and not possible)) if equal, quit flow. Why won't this work?

Add a merge before the retrieve action and point to the merg instead of the retrieve.
