I think I am close I just don't know the exact syntax.
I am trying to use VBA to select a record based on the value of the SCID (Primary Key) from my table Stock Conversion.
If LookUp("Source PC", "Stock Conversion") Is Null Then
sc1.AddNew
sc1.Fields("[Source PC]").Value = Me.cmbSource.Value
sc1.Update
End If
This is the code I have now, as you can see I only want the field to be populated if the value is Null. It needs to find the Source PC where SCID = Record.
Thanks in advance, Bob P

This is where you should use a recordset.
Dim rs As DAO.Recordset
Dim sSQL As String
'SQL to select a record from a table MyTable based on a field or control
'called ID in the current form
sSQL="Select Id,Field1 from MyTable Where Id=" & Me.ID
'Open the recordset
Set rs = CurrentDB.OpenRecordset(sSQL)
'Test for End Of File to see if the recordset is empty ...
If rs.Eof Then
'add a new record
rs.AddNew
rs!Field1 = "Something"
rs.Update
Else
'... otherwise, do what you want with the record,
'let us say edit.
rs.edit
rs!Field1 = "Something"
rs.Update
End If
