My question is on validation of dates in SharePoint… If i have two date fields – start date(& time) and end date(&time). How do i validate these, so that a person cannot pick a time in between these? For example, if someone picks friday, 15th of June, 8-11am, another wont be able to pick friday 15th of June, 8-12pm or 8:30 – 10:00am or any time in between.
This involves comparing the current column with previously entered ones, how do i do this? I just got started on SharePoint.
Thanks in anticipation and kind regards
