Thanks for the reply... much appreciated.
I was reporting expensive using a chart of accounts I created.
I had a column defined for the amount and another as to the type of expense.
i would then categorize the type column and get subtotals for each type of expense.
My spread sheet was functioning as a set of books for my small business.
I used column categories to generate many reports such as sales, accounts receivable expenses fixed assets and so on.
My UMBERS 3 column tab has no category insertion option listed in the pulldown list. The numbers 3 help text says it should be there but it is not.
I have fallen back to numbers 2 and will continue to use it I guess.
I Just think the roll out of el capitan was poor or premature
It blew away my printer software for both my printers (hp and canon) and this new numbers has now added to the frustration..
Any road, thanks again for the reply and I guess I will be checking the updates for fix.
