Please attach a sample workbook. Make sure there is enough data to demonstrate your need. Make sure your desired results are shown, mock them up manually if necessary. Remember to remove ALL confidential information first!!!

However, nothing on this Forum works quite as well as you might expect. The attachment icon doesn't work!! (Helpful, isn't it!!). Instead, just before you submit your post, click on GO ADVANCED (near the bottom) and then scroll down to Manage Attachments to open the upload window. The relevant instructions are at the top of that screen.
