I have a site where employees input schedule items, each with a Start Date and End Date. I would like an error message to appear when users select an End Date before the Start Date. What formula can I use under Column Validation settings so that the user has to choose an End Date that is greater than or equal to the Start Date column?
I have already done this in the List Validation Settings, but I would like to validate by column so that the error message appears by the End Date field rather than at the bottom of the form.
