Summing month to date of values in multiple columns

Hi all,

I am trying to sum up the month to date of values in cells.

I need to find a way to lookup current month date and sum values in multiple columns from the start of the fiscal(business cycle) year to current month of the year.

So if the current month is July then the year to date value is the sum of values in say column b to column h from January to July 2013.

The past year to date will be January to July 2013.

I have attached an example to give a bit more of a guide.

Any ideas?
