Needing help with "Set" node

Hello! I need a bit of help with the “Set” node / how to merge multiple of these later.

My use case is to post something on multiple social media posts once a Trello card is moved. Before posting, the flow goes through a list on Trello and should set variables with an universal caption that is put under every post. For each platform, there’s a different caption.
I tried achieving that with three If nodes and three Set nodes immediately after them, like below.

Now comes the problem: When merging them so I can call the captions in the flow later, the flow errors in the next node: The "url" argument must be of type string. Received undefined.
Before, I forgot to merge the three lines, and the flow (except the captions) worked.

How would I correctly get all my Set nodes into use? Or is there a better solution for my use case?

Thanks in Advance :slight_smile:

Hi @tomato_planet

Have you tried setting the Merge Node’s Mode to Multiplex?
