Node only execute if in path of IF Switch

I'm making a workflow that will take many files uploaded by the user.  I first take a boolean input for whether or not the user wants to upload a file or use the default.  Depending on that boolean I either want to ask them to upload a file or it will simply use the default.  (The goal is to make this very user-friendly on the Web Portal).  I want to throw my File Upload nodes in my IF Switch, but they don't have inputs, but simply variable outputs.  How do I make them follow the if switch as well?


Thanks for your help!

Hi Aro, can you make a screenshot?

General: connect the flow variables to the flow variable ports. Those are on default hidden.

Best, Iris
