Dcount getting runtime error '2471'

[Vasago]

Bookings ID is number
ID is autonumber
Error says:
Run-Time error '2471':
The expression you entered as a query parameter produced this error: '[Bookings ID]'

If DCount("[Click ID]", "Access Click log", "[Bookings ID] = " & Forms![Roll Out CRM]![Royal Rollout AM Routes]![ID]) = 0 Then

Thank you for the help!

If booking id is a string, you will need to surround the value you're looking for in quotes.

[Vasago]

Booking ID's type is a number along with ID

Then you will need to post the full exact error message.

- The string theory:
You've stumbled upon one of my pet peeves by building the criteria string within the command - and it's not your fault because that's how a majority of examples show how to use the command.
Instead I suggest that you build the string first and then use the string in the command. Why you might ask, because you can then check how the string is actually resolving; thus, making troubleshooting the code so much easier as most of the time the issue is with something missing or not resolving properly/as expected within your string.
So to use your code:

'>The following is air code; thus, not tested and may require more effort to operate properly
'
    DIM strSQL as string
    Dim intCount As Integer
'
'
    strSQL = "[Bookings ID] = " & _
        Forms![Roll Out CRM]![Royal Rollout AM Routes]![ID]
'
'now you can insert a debug print here for troubleshooting
' - press <ctrl><g> to open the immediate window
' - you can now cut and paste this information for review!
'
debug.print "Your criteria = " & strSQL
'
'now use the string in your code:
    intCount= DCount("[Click ID]", "Access Click log", strSQL)
debug.print "Your Count= " & intCount
'
'Note: I didn't return the count within the IF...THEN...
'once again because troubleshooting the code is not easily 
'done when the function returns within another 
'function/statement.
'
'
    if intCount = 0 then
        'the remaining code
    end if
'
'

If you will make these little changes and post back the resolved string we can help you tweak the code.

When posting errors:
Please post the EXACT title, number, and text of the error message. Please do not alter, omit, nor abreviate the information provided in the error message. ALSO indicate on which line of the code the error occurs and provide enough code so that we have the context of the commands used.

ZMBD,

I can't thank you enough for you time, education and knowledge. I have included the code below. My debug print for strSQL is Your criteria = Bookings ID = 2110. This is the correct Booking ID number.

Error Code on line 9:
Run-time error '2471':
The expression you entered as a query parameter produced this error: '[Bookings ID]'

Private Sub Form_AfterInsert()
Dim db As Recordset
Dim strSQL As String
Dim intCount As Integer

    strSQL = "[Bookings ID] = " & _
        Forms![Roll Out CRM]![Royal Roll out Field Trips]![ID]
Debug.Print "Your criteria = " & strSQL
    intCount = DCount("[Click ID]", "Access Click log", strSQL)
Debug.Print "Your Count= " & intCount
If intCount = 0 Then
Set db = CurrentDb.OpenRecordset("SELECT * FROM [Access click Log]")
db.AddNew
db![Booking ID] = ID
db.Update
End If

Zmbd,

I can't thank you enough for you time, lesson, and knowledge. My debug print for strSQL is Your criteria = [Bookings ID] = 2113. This is the correct Bookings ID.

I am getting the error below on line 9.

Look at two things:

-- Open the table "Access Click log" where[Bookings ID] is located.
Check that the field name is spelled correctly between the code and the table.

-- Check the type cast of the [Bookings ID] field, I suspect it is set to "text" not numeric as you are expecting.

ZMBD,

Thank you again for your help. Problem is solved and I feel extremely embarrassed. [Bookings ID] is suppose to be [Booking ID].

Thank you,
