Can anyone find my mistake?

I'm using the following code to create one of two possible recordsets, depending on the value in another form. This is using an SQL7 database via ADO. The first possibility (Shop Orders) works fine; the second continually gives me "Item cannot be found in the collection corresponding to the requested name or ordinal". It fails on the "open" statement. Using Query Analyzer, I can run the Stored Proc (sel_styles) and it works fine. Can anyone figure this out???

Code:

---

    Dim rsListing As New ADODB.Recordset
    Dim objCmd As ADODB.Command
   
    Set objCmd = New ADODB.Command
    With objCmd
        .ActiveConnection = PROJ_DB
        .CommandType = adCmdStoredProc
        If frmShopOrder2.txtShopOrderNo = "?" Then
            .CommandText = "sel_shoporder"
        ElseIf frmShopOrder2.txtStyle = "?" Then
            .CommandText = "sel_styles"
        End If
    End With
    With rsListing
        .CursorLocation = adUseClient
        .CursorType = adOpenKeyset
        .Open objCmd
    End With
    Set objCmd = Nothing
