I am looking for help with my formula. It is in a formula date field

WorkdayAdd(ToWorkDate(ToDate("[Factory Order - Order Date]")), 91)

QB is telling me that it needs a date ("expected date") even though I know the field is a date field that I am referrencing.

Can someone help me understand why this isnt working?

Thank you.
