I'm quite used to working with pivot tables but not good at creating them so
please go easy! I have36 columns of monthly data displayed jan06, feb06 etc
and I would like to group them into years so I can expand/collapse them as
required (BY YEAR)
At the moment I have to select/deselect each column. It would be easier to
select the relevant year and deselect as requireD

How do I do this? Please help
