Dlookup issue

P: 4
I have created a form to lookup components in a table. The problem I am having is the table I have has multiple designations in the same field. Ex CR2,CR4,CR18
If I am looking up a field that has one designation in it I am fine. But if the field has more than one designation in it, my Dlookup returns no information. Some of these fields have more than 50 designations in them. So I am trying to avoid creating new individual records. I will if I have to thou.

Private Sub txtReference_Designator_1_Exit(Cancel As Integer)
Dim X, Y As String
On Error GoTo ERR_txtRef_Desig_1
Forms![frmFailureUpdate]![txtPart_Number_1] = DLookup("LIKE *[COMPANY_PN]*", "Tbl" & [lbCode_Name] & "PartsList", "[REF_DESIG] = Forms![frmFailureUpdate]!txtReference_Designator_1")
Exit Sub
ERR_txtRef_Desig_1:
MsgBox "Information not available. Contact Administrator"
Exit Sub
End Sub

Try with DFirst
or Dlast

it's the same structure as Dlookup

Also, look out for your usage of DLookUp. Your parameters are not set up in the correct order.

DLookup(expr, domain, [criteria])
The DLookup function has the following arguments.

Argument Description
expr An expression that identifies the field whose value you want to return. It can be a string expression identifying a field in a table or query, or it can be an expression that performs a calculation on data in that field. In expr, you can include the name of a field in a table, a control on a form, a constant, or a function. If expr includes a function, it can be either built-in or user-defined, but not another domain aggregate or SQL aggregate function.
domain A string expression identifying the set of records that constitutes the domain. It can be a table name or a query name for a query that does not require a parameter.
criteria An optional string expression used to restrict the range of data on which the DLookup function is performed. For example, criteria is often equivalent to the WHERE clause in an SQL expression, without the word WHERE. If criteria is omitted, the DLookup function evaluates expr against the entire domain. Any field that is included in criteria must also be a field in domain; otherwise, the DLookup function returns a Null.
