Error Trying To Populate ListBox With A Named Range

[Ark68]

I am trying to use a named range as the source of items for my listbox. This line creates the named range. It's in a standard module in my workbook.

Workbooks("Sports17.xlsm").Names.Add Name:="data_file_list", RefersTo:="=OFFSET('[" & wb_sched.Name & "]" & temp_ws.Name & "'!$B$1,1,0,count('[" & wb_sched.Name & "]" & temp_ws.Name & "'!$A:$A),2)"

The named range is named "data_file_list" and refers to a range in a second workbook (wb_sched, worksheet temp_ws) columns B and C. Data fills these columns from row 1 (header) to 165.

This is the code in which I populate the listbox.

With .uf1_listbox1
            .ForeColor = RGB(0, 52, 89)
            .Clear
            .ColumnCount = 2
            .ColumnWidths = "75;25"
            .List = Range("data_file_list").Value
            .ListStyle = fmListStyleOption
            .Locked = True 'do not unlock until missing rentals are 0
        End With

I receive a "Method 'Range' of object '_Global' failed." error with the line in red.
