You may choose to click the filter at the top of Column 'N' (which is Cell N2), and deselect 'Blanks' from the drop-down filter menu. Click 'OK' in the drop-down menu. You now view only the items that you have ordered. All the other rows in the spreadsheet are hidden, but they are not deleted.
If you are using a computer device that doesn't allow you to save the file, the best way to place an order is to email me the species name and the Euro price of each shell that you want. No other information is needed. Please do not quote the 'row number', because row numbers are generated automatically by Excel and they do not uniquely identify a shell.
