Conditional sum based on X date

[Gonzo346]

Dear all, I can't think of a workaround for this issue;

I have a table with an allocated monthly budget (Jan=4; Feb=2; Mar=3; Apr=10) and want a formula to find out which is my Year to date x budget. For example; in Jan, the sum would be 4; in Feb would be 4+2=6; Mar 4+2+3=9, etc.

Any ideas which may point me to the right "thinking" direction would be greatly welcome.
Cheers and a great weekend

Makes sure row 1 contains actual dates (1/1/11,1/2/11 etc) rather than text("Jan","Feb)
