Populate GET parameter value from "Properties" step in TestSuite.

I'm very new to using the Test Suites in SoapUI. So before I go into detail, I'm using version 5.7.2 of SoapUI and in the process of testing an API proxy.

The issue I have is when I send a POST request, I get the response as this: ["92980"]

I was exploring how to get values from the Property Transfer and found in another post of using "$[0]" to get the specific value, which I've done and stored into a "Properties" step.

My Goal is to get that value of 92980 into this:

I don't know if I can do this within the "Property Transfer" step or if it can be done in the "Properties" step or if there is something I'm unaware of at this point.

I'm going to keep digging to find a solution, but hopefully someone will have a solution for this.

Thanks, Michael
