SUMIFS #REF! error message
I have had a spreadsheet for years where I have one table reference another table of values and test with the SUMIFS function. It worked fine until recently when now I get "The formula contains and Invalid reference" message. Nothing otherwise has changed with the tables. I have tried deleting the formula and re-entering only to get constant REF error messages.
Is this a new, common bug and is there a fix/workaround or do I wait for an update of Numbers?
