I am trying to work out the difference in minutes between two dates and times, and having tried many a solution presented on here nothing seems to work...
When trying to use the 'Ticks' expression' I get the error that the datetime string is not valid even though as far as I can tell it is in the ISO 8601 format
I have included the full flow of the section I am working on below. I am assuming it is something simple but I don't work a lot with dates and I am stumped!
