It would help if you attached a sample Excel workbook, in which you can show how you envisage the file working by mocking up some sample data.

To do this, click on Go Advanced (below the Edit Window) while you are composing a reply, then scroll down to and click on Manage Attachments and the Upload window will open. Click on Browse and navigate to (and double-click) the file icon that you want to attach, then click on Upload and then on Close this Window to return to the Edit window. When you have finished composing your post, click on Submit Post. Do not try to use the Paperclip icon, as it doesn't work on this forum.

Here's an example of a calendar file that I submitted to another poster a few hours ago (in Post #9):

It might give you some ideas on how to proceed.

Hope this helps.
