Excel: Dynamic sum (non contiguous range)

Dear all I have the following spreadsheet

[TR] [TD="colspan: 5"]
https://1drv.ms/x/s!Av0OR27GDzktgUPrcRv_W6YdhOjy[TABLE="width: 336"]
[/TD] [/TR] [/TABLE] I would like to create a formulae in T4 based on a dynamic value placed in cell T2. My target is to calculate Sum all months to get to a YTD value (YTD=year to date) . Example: May 16 YTD = January+ February+March+April+May The issue that i have is that i need to ignore the greyed cells ( cells that sum quarters) I tried with OFFSET But it doesn't ignore particular cells. thanks in advance Antonio
