Dlookup check

[Abhean]

Need some help/pointer. I am attempting to search a table/field to see if it matches a field in a form.

This is not working for me. I am just looking to hard, but reaching out.

If Me.Txt_field = DLookup("[field]", "Table", Preset_variable) Then
   'found it
Else
   'didnt find it
 
End If

The basic construct of the code seems fine. We don't see what data you're working with, nor what you mean by it failing, so that's as far as we can go for now.

What is contained in Preset_variable?

Let's double-check a few things. What is the name of the table you are searching? What is the name of the field in the table? "Preset_variable" doesn't look like a comparison test.

Hi All

Long time since I posted here!

Not withstanding the previous replies, may I suggest this or similar may help

If DCount("[field]", "Table", "[field] = " & Me.Txt_field) >= 1 Then
   'found it
Else
   'didnt find it
End If

As you just need to know if it exist (at least once), I would use DCount() as DLookUp() will return Null if nothing is found. This of course can ne worked round if absolutely necessary.

Above assumes Txt_field is numeric.

I could be totally wrong, but just a thought.

Sorry for the delay. I am attempting to check a table to see if an email is already in the table.

It appears that the code is always giving a true response.

And please do not blast me for the naming. I know. :)

Dim FullEmail As String
Dim EMName As String
 
'Prepare the email, Strip first initial from first name
     initial = Left(LTDLastName, 1)
    'Combine first name w/ last name initial
     EMName = [FirstName] & [initial]
    'Add @labtechdiagnostics after combination
    Me.LTDEmail.Value = [EMName] & "@LabtechDiagnostics.net"
    'Check Email
    'set full email for lookup
    FullEmail = Me.LTDEmail
        If FullEmail = DLookup("[LTDEmail]", "LTDEmail", Me.LTDEmail) Then
                MsgBox "This Email has already been used. Please modify this one." _
                       & vbCr & vbCr & "Please modify Email.", vbInformation, "Duplicate information"
                 Me.LTDEmail.SetFocus
            Else
                MsgBox "Did not Find that Email"
 
        End If

Try this modification:

If FullEmail = DLookup("[LTDEmail]", "LTDEmail", "[LTDEmail] = '" & Me!LTDEmail.Value & "'") Then

See if Quotes (') and Double-Quotes (") - Where and When to use them helps.

I won't. Please understand though, that if/when we do draw your attention to things like naming and code indenting it's because we understand how getting it wrong can lead to extra levels of confusion and difficulty for you. If something's simple then you won't struggle so much with it. Naming and code indentation help you to read what is there and understand it more easily. Their benefits are not restricted to that but they certainly do go to make your life easier, quite apart from ours when we want to help you.
