My slack message formula keeps out putting the word "model"

here is my formula:
thisRow.[Step 1 Result].Format("{1} changed to {2}", Task, thisRow.Status)

and it keeps outputting to Slack
this task changed to model

any help is appreciated

The first argument of Format is the template. By chaining (using the thisRow.[Step 1 Result].Format(...)approach) you’re passing thisRow.[Step 1 Result] as the template.

Try:

Format("{1} changed to {2}", [Step 1 Result].Task, [Step 1 Result].Status)
