mac numbers 2.1 not compatible with iPad numbers
I originally created a spreadsheet on my Mac - Maverick and sent it to my iPad to update regularly and easily. I sent the updated version to my computer via email. When I try to open the attachment in the email, it will not open and I have a window which tells me to download the latest version Mac Software. I do not wish to download Yosemite. How can I update the spreadsheet on my computer without downloading the latest mac software. Please can you help
