Using Variables Defined in Flows for Request

I am setting up a flow to test some API endpoints, and I am running into a problem consuming/setting the variable for the request.

Let’s say, I set up a data field with a value of I then linked it to a set variable block that sets a variable named server. I defined my start entry point, where I perform a get variable on the server. I then add my send request pulling in a request from my collection. I can see the server variable listed in the send request box and I link the get variable server to the server variable in the send request.

In my request, I have the url set up as follows:

However, when I run the flow, the url that is getting hit isn’t adding anything in the {{server}}, which from what I understand should be getting set via the get variable and passed to the call. Am I doing this right?
