Hi ,
I am trying to create a rule to validate the entered Startdatetime and Enddatetime are falling within the already booked datetimes in the same list .
Can you please guide me the right way to do so ?
Any suggestion is greatly appreciated .
Let me know if you need any additional information.
My question is related to this video-- Prevent overlapping date periods in SharePoint list(https://www.youtube.com/watch?v=1WSF-amgVBE)
Can anyone tell me how did he write the rules for it?
