The link is not working for me.

To attach a file to your post,
click advanced (next to quick post),
scroll down until you see "manage file",
click that and select "add files" (top right corner).
click "select files" find your file, click "open" click "upload" click 'done" bottom right. click "submit reply"

Once the upload is completed the file name will appear below the input boxes in this window.
You can then close the window to return to the new post screen.

After you upload an actual Excel workbook, please explain why Personal hobbies should return 8. From the picture, I only see one cell in the Personal hobbies row with something in it.
