Luacom and Excel borders

[HobbsyJr]

I'm using luacom to manipulate excel files with a degree of success but i cant seem to change borders on a range of cells.

So far i have:

oExcel = luacom.GetObject("Excel.Application");
Book = oExcel.Workbooks:Open(_DesktopFolder .. "\\document.xlsx");
Sheet = Book.WorkSheets(1);

RangeRef = "A3:E" .. nEntries + 3
local BorderList = Sheet:Range(RangeRef)

BorderList:Select();

I know the next part is something like this:

BorderList.Borders(xlEdgeLeft).LineStyle(xlContinuous)

but i get errors returned:

"Error: "

Anyone with any experience with luacom and excel out there?
Thanks
