Flag if Multiple Dates in Same Column
I'm attempting to set up conditional formatting to highlight cells if there are duplicate dates in the same column. (For a spreadsheet managing event bookings, want to highlight if multiple requests for same day)
I tried an IF/COUNTIF function in a new checkbox column but I keep getting #UNPARSEABLE.
- Column name is Mtg Date
- Formula I tried: =IF(COUNTIF(Mtg Date:Mtg Date, Mtg Date1) >1, 1)
- Would then set up conditional formatting to highlight if box is checked
The ultimate goal is that if dates are entered that match each other I'd get a flag so that I can make sure the same room doesn't get booked. Any help?

your issue is you have a space in your column names. When there is a space in the column names you need to put the name in hard brackets.
=IF(COUNTIF([Mtg Date]:[Mtg Date], [Mtg Date]1) >1, 1)

I didn't realize that was a rule! Thank you!
