400+1200=1600, but 400+1600=2000. I was under the impression that you wanted a random duration between 400ms and 1600ms, not between 400ms and 2000ms
Also, I’m just realizing that I reference that variable in a function in .set on the Var element, and because timerd1duration is set in a Template environment, by the time the function from set is executed it will always have the value it got in the last generated trial, so my code won’t have the desired outcome.
