VBA to add one column by all values of the adjacent 8 columns and three rows once each

Hi,

I can't really wrap my head around how to do this or if there's even a formula or even a macro i could run to run this data.

I have three rows of data (29-31) from columns D to Q.

I would like to take D29 and add each of the values in the adjacent columns exactly once and sum up the value D thru Q

For example I'd like to return not just Sum(D29:Q29) but also Sum(D29:R29)+Q30, Sum (D29:R29) +Q31.

Could anyone on this board think of a way to help me write a macro that would add these values?

That is D29 + E29 or E 30 or E31 + F 29 or F 30 or F 31 + G 29 or G 30 or G 31... and on?

Even though I wrote "or" above, i would need the other values to be added in a separate calculation, until all possible permutations of D and the following 8 columns and 3 rows of data are exhausted.


It's impossible to me,
But you guys are way better than I am!
