Set Value of Reference Field via Workflow

[sarahyelton]

I am scripting novice and pretty much take something someone else has done and try to figure out how to use it for our purposes.  🐵  I have a workflow where, in one step, I attempt to set the value of a reference field (u_application) with whatever value is captured in a reference variable (CCRchangeapp).  From what I have read, we need set via sys ID but I have no idea how to do that.  This is what I currently have . . . can someone please tell me what I need to change?

Doh!  I was using a Lookup field type on the variable.  I previously had it as a reference.  Once I changed it back, it works!!!!  Woo hoo!
