Text File import program not functioning

This code is from an edited macro & is designed to import a text file which is stored automatically with a date based name

"Ext" reffers to pre defined file extention string, and the FileName string is made up of information from cells in the spreadsheet. I have tested this string and it is producing the correct filename (I think!).

The code will not function and I can't figure out why. When I debug, it highlights the final line " .Refresh BackgroundQuery:=False". Any fix or alternate code sugestions would be very welcome.

Dim FileName As String
FileName = "TEXT;\\dd-001093-c\PressFiles\frf5600\Furnaces\Furnace" & Sheets("Control").Range("J6").Text & "\" & Sheets("Control").Range("G7").Text & Ext

    Sheets("Data").Select
    With ActiveSheet.QueryTables.Add(Connection:= _
    FileName, _
        Destination:=Range("A1"))
        .Name = Sheets("Control").Range("G7")
        .FieldNames = True
        .RowNumbers = False
        .FillAdjacentFormulas = False
        .PreserveFormatting = True
        .RefreshOnFileOpen = False
        .RefreshStyle = xlInsertDeleteCells
        .SavePassword = False
        .SaveData = True
        .AdjustColumnWidth = True
        .RefreshPeriod = 0
        .TextFilePromptOnRefresh = False
        .TextFilePlatform = 850
        .TextFileStartRow = 1
        .TextFileParseType = xlDelimited
        .TextFileTextQualifier = xlTextQualifierDoubleQuote
        .TextFileConsecutiveDelimiter = True
        .TextFileTabDelimiter = False
        .TextFileSemicolonDelimiter = False
        .TextFileCommaDelimiter = False
        .TextFileSpaceDelimiter = True
        .TextFileColumnDataTypes = Array(1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1)
        .TextFileTrailingMinusNumbers = True
        .Refresh BackgroundQuery:=False
    End With
End Sub
