Happy New Year eveyone, I hope you all had a great holiday.
My first and definitely not last post of the year
I had to research this formula a bit to figure out how to stop duplicate sessions being created, I found this and implemented it into my app and it works great.
NOT(IN([Ref], SELECT(Case Session[Ref], [Date]=[_THISROW].[Date])))
There is one downside to this formula that it will not let me update or change any detail regarding the session as it thinks that the session is already there. How would I go about amending this formula so that If wanted I could change the time of the session even if it is on the same day?
