On a button’s actions, I want to create a new row where one of the fields is set to a parameter that is passed to the page by URL. Can I use the {{$Param.label}} merge syntax to set this value?
Yes. Merge Syntax allows for this.
Is this also true if the URL parameter is being passed through a Page Include? The actions I have in the screenshot are not working when the parameter comes from a page include. Works fine if I go to the page directly. I did confirm that the yieldid value is being passed correctly on the page include. 
Unfortunately, Page Includes don’t pass page URLs.
Ahh. That explains it. I’ll go a different route… Thanks.
