Using Duration in an Automated Email

I want to insert data from a form to an auto reply that is a duration (hh:mm) volunteered. However it sends in seconds. So I made a formal field to divide into hours. The formula field is just blank. I know I can’t use look up fields but I also can’t use formulas?

Thanks

Welcome to the community, @JanData! :smiley: A formula should work. Could you please share the formula that you tried?
