Error when trying to use Local Variable in Test Object

SO as the title suggests I’m trying to use local variables inside Test Objects ‘text’ contains property. I have the below in my Object that I need to be dynamic:

but whenever I try to get my test to click on it, it responds with: =============== ROOT CAUSE =====================
Caused by: com.kms.katalon.core.webui.exception.WebElementNotFoundException: Web element with id: etc etc.

If I change the variable back to a set number, it works no problem, so I’m not quite sure where I’m going wrong here
