What is wrong in the Code (1 Viewer)

Cnt = DCount("Mob", "QOCCUPATION", "DepartureDate = Me!sfrRoomOccupations.Form!DepartureDate")

Your criteria Me!sfrRoomOccupations.Form!DepartureDate is part of the string, you have to concatenate it.
And take care to provide the correct format (#).
See here: Date and time criteria from a control on a form

Cnt = DCount("Mob", "QOCCUPATION", "DepartureDate = #" & Format$(Me!sfrRoomOccupations.Form!DepartureDate, "mm/dd/yyyy") & "#")

Cnt = DCount("Mob", "QOCCUPATION", "DepartureDate = #" & Format$(Me!sfrRoomOccupations.Form!DepartureDate, "mm/dd/yyyy") & "#")

Thank you sir, its parfectly working
Sir, if I put another condition
Cnt = DCount("*", "QOCCUPATION", "DepartureDate = #" & Format$(Me!sfrReservations.Form!DepartureDate, "mm/dd/yyyy") & "#" And [Mob] = Form!frmOccupants!TXTMOB)

frmOccupans is the Main form and Mob is number field, but error is coming

 

[arnelgp]

try:

Cnt = DCount("*", "QOCCUPATION", "DepartureDate = #" & _
Format$(Me!sfrReservations.Form!DepartureDate, "mm/dd/yyyy") & "# And [Mob] = " & Form!frmOccupants!TXTMOB)

Note: Format(DateValue, "mm/dd/yyyy") can build a string like 03.16.2024 (depend on date format ... / is the date separator in Format function).
=>
Format(DateValue, "mm\/dd\/yyyy") or with ISO format Format(DateValue, "yyyy-mm-dd")

Put your criteria into a string variable, then debug.print it until you get it correct. Then you can use that in the function.
If you still cannot see your error, you can post the code and the output back here.
