    Only add missing fields to table from another Table?

    I am only trying to add fields that don't exist in the table already from another table list. It works if all the fields are missing but when i already have that field in my table, i get an error. How can i limit the Add column to only the fields that are missing? Any help will be greatly appreciated.

    Function AddField()

    Dim db As Database
    Dim tbl As tableDef
    Dim fld As DAO.Field
    Dim Str As String
    Dim sName As String
    Set Criteria = CurrentDb.OpenR ecordset("Crite ria Table")

    Set db = CurrentDb
    Set tbl = db.TableDefs("C opy_TEstTable_t est")

    If Not (Criteria.EOF And Criteria.BOF) Then
    Criteria.MoveFi rst
    Do Until Criteria.EOF = True
    Str = [Criteria].[Linked Table]


    Criteria.MoveNe xt
    For Each fld In tbl.Fields
    If (fld.NAME) = Str Then

    Debug.Print fld.NAME; Str
    Else

    Str2 = "ALTER TABLE Copy_TEstTable_ test ADD COLUMN " & Str & " TEXT(25);"
    DoCmd.RunSQL (Str2)
    End If
    Next fld
    Loop
    Else

    End If



    Criteria.Close 'Close the recordset
    Set rs = Nothing 'Clean up

    End Function
Working...
