Question
QUESTION: I have a subform with the emplid as the first feild. when they tab it does the Dlookup.  If it can't find the first name it sets the value of emplid to spaces.  I want it to go back to the emplid so they can start over.  Right now it goes to the feild i tabbed to.  

Private Sub EMPLID_AfterUpdate()

EMPLID.SetFocus


If IsNull(DLookup("[FNAME]", "candidates", "emplid = LMPeople")) Then
MsgBox "No records were found. Please try again."
LMPeople = "   "


Else
Me.[First Name] = DLookup("[FNAME]", "candidates", "emplid = LMPeople")
Me.[Last Name] = DLookup("[LNAME]", "candidates", "emplid = LMPeople")
Me.[short Desc] = DLookup("[dept_descr_short]", "candidates", "emplid = LMPeople")
End If

End Sub


ANSWER: First, don't set your field to spaces. That's just bad practice. Set it to EMPTY: ""

Of course, you'll have to set the "Allow Zero Length Strings" property of that field in the table to TRUE.

Now, all you really have to do to fix your problem is just issue a DoCmd.GoToControl command after your MsgBox.

DoCmd.GoToControl "FNAME"

If that's the name of your text box.

QUESTION: I tried DoCmd.GoToControl "LMPeople" it doesn't appear to work The field is named LMPeople on the subform.  In the field preferences the control is LMPeople, but I get an error runtime 2109 stating that LMPeople is not a field in the current record.  In the Dlookup I am using that field name to find my value.

Answer
If you want to refer to a value on a Form, you can use the notation:

Forms!FormName!FieldName

You can use this notation inside of queries, other forms, or even reports. I have a free tutorial that explains how to use this:

Note that if you're refering to a value on a SUBFORM, the correct notation is:

Forms!FormName!SubForm.Form!FieldName

Crazy, I know. Enjoy! Hope this helps.
