Hi Guys,

Could you possibly help with the following please?

Can I do a comparison to the same time period last year?
So if the sheet is calculating the spend per supplier between Jan 17 to April 17, i like it to calculate the same time period a year previous i.e. Jan 16 to April 16.
If i load the sheet up in September it will compare Jan 17 - Sept 17 with Jan 16 - Sept 16.
Once i have this information i would like to show it as a percentage increase or decrease.
Is it possible to do this as one formula?
