Get time between two triggers?

EC, if i may can i just clarify a couple of things, this is my set up, I’m just trying to make sure I’ve followed correctly:

My macro needs a title parameter and the print string doesn’t say “in development” as yours does, I’m using 4.15?

Also have I correctly set the inputs and outputs within the macro correctly?

I’d really appreciate your advice.

A million thanks again!
