Try .Sheets.Count

In Excel, use the VBA Object Browser and drill down to sheets. You should get the details there.
I know Excel defaults to 3 sheets when it opens a new workbook, but you are opening a old file.
If you are addressing a sheet by using the name Excel has assigned, be careful.
I have seen Excel change the 'Sheet 1' to 'Sheet 2' when I created a chart. All my data references for the chart were pointing to Sheet 1. I assigned Sheet 1 a name and referred the sheet name and everything worked fine.
