If a record doesn't exist

Emma

I am trying to set up the next record on the button if it is blank to get the
highest number and put it in the Client ID field. Here's my code which isn't
working:

Private Sub Command116_Click()

On Error GoTo Err_Command116_Click

Dim intNewID As Integer
Dim strSQL As String
Dim strSQL2 As String

On Error GoTo Err_Command116_Click

'See if Client ID exists if not get new one

If ![Tbl Client Information].[Client ID] Then

'Find the current high number and Add 1 to it

intNewID = Nz(DMax("[Client ID]", "[Tbl Client Information]"), 0) + 1

'Write it to the table ASAP to avoid duplicates in a multi user environment

strSQL = "INSERT INTO [Tbl Client Information] ([Client ID]) SELECT " &
intNewID & ";"

CurrentDb.Execute strSQL, dbFailOnError

'strSQL2 = "INSERT INTO [Tbl Client Information] ([Status]) SELECT
Active;"

'CurrentDb.Execute strSQL2, dbFailOnError

'Make the new record the current record

Me.Requery
With Me.RecordsetClone
.FindFirst "[Client ID] = " & intNewID & ""
If Not .NoMatch Then
Me.Bookmark = .Bookmark
End If
End With
Me.Status.Value = "Active"
Me.Combo157.Value = "Canadian"
Me.Children.Value = "0"
Me.Other.Value = "0"
Me.[Family Profile].Value = "0"
Me.[Marital Status].Value = "0"
Me![Intake Coordinator].Value = CurrentUser
End If


DoCmd.GoToRecord , , acNext

Exit_Command116_Click:
Exit Sub

Err_Command116_Click:
MsgBox Err.Description
Resume Exit_Command116_Click

Is there any reason why you don't want to use an autonumber to handle Client
ID?

Emma

I'm already using the autonumber for something else

You can have more than one autonumber :]

Your problem *might* be this line of code:

If ![Tbl Client Information].[Client ID] Then

Is the form bound to 'Tbl Client Information' ? If so try this:

If isnull(Me![ClientID]) Then

Emma

I'm having a problem checking if the ClientID Exists in this line If ![Tbl
Client Information].[Client ID] Then
also I'm getting can't find the field '|' referred to in your expression.

I am using an autonumber but for some reason it keeps coming up with a blank
which turns into the number 0. So the number 0 already exists so I can't have
a duplicate and I'm getting an error there that's why I'm trying to do it
this way.

It sort of looks like you're trying to use a C-style 'not' logical operator
there. If so, VB uses "Not" instead. This also won't work unless your
ClientID fields have a default value of zero, otherwise they will default to
Null and your test will fail every time, probably with an "Invalid use of
Null" error.

Also, you should probably check if the ClientID exists for the current
record or for one specific record. You can use DLookup to do this pretty
easily. Its syntax is simliar to the DMax function that you used elsewhere.

Another thing is

Change it to

Me![Client ID]

Just a reply to this statement. NO, you cannot have more than one autonumber
in a table. At least with Access' native JET engine and I suspect with most
(if not all) other database engines.

That is true, but you can join tables using queries, and in that sense you
can use more than one autonumber. If your tables are properly normalized,
you should never even need to have more than one autonumber per table.
