Why "Extract time in status" with Adaptavist not works?

[Alex]

Hi all! i am trying to run the code from the link

  https://library.adaptavist.com/entity/count-the-time-an-issue-was-in-a-particular-status  

But I am getting  time "0"

You have the output template set to multi-line text.  Try changing it to "duration"

Ok, that suggests your calculation is actually the problem.

Is your status definitely called "TO DO" (the = is an exact string match), and the test issue has been through that status at least once (and moved into another status)

After checking those two, the next thing is to insert log lines in there, so the log tab tells you what the contents of variables are as it works through
