May I please ask you about this - I cannot “save” my work on my excel spread sheet anymore apparently because it’s an older version. What can I do?

Looks like you are opening a document first created with an almost twenty year version of Excel. Obviously, newer versions will want to save the shreadsheet in a slightly different way. The new standard .xlsx replaces the old standard .xls. You're most likely using a much newer version of Excel so when you go to save, you might try choosing "save as" then you should be presented with the ability to save the document in one of many newer formats including .xlsx.

You can also check to make sure that your version of Office is up to date. There's a "check for updates" in one of the drop down menus at the top.
