Sum data based on coordinates

[chris3131]

	a	b	c	d
1	5	2	7	100
2	10	4	14	200
3	15	6	21	300
4	2	8	28	400

If I have a table like the one above with column and row headers...NB. these are not the Excel headings, they are specific to the table and could appear anywhere on a worksheet.
I want to be able to specify coordinates (single, multiple, rows and columns) and have a consistent formula return the sum.
eg.
b3: formula returns: 6
b3,c2: formula returns: 20
d1:d3: formula returns 600
a2:d2: formula returns: 228

I don't mind how the coordinates have to be written in order to get the appropriate formula to work.eg. the row/column coordinate can be in a single cell, or in separate cells. However what is key is that the user is able to enter those coordinates in a consistent manner and have a consistent formula return the result.

Similar tables will be on multiple worksheets, so I would like the user to also be able to specify the worksheet and have the consistent formula return he value from the right table on the right worksheet. If range names can but used to reference the dataset/row headers/col headers then all the better.

Thanks in advance

Great solution Dante. But unfortunately I need a non-VBA way of doing this....if that’s possible??

See if this does what you need

Formula in N2 copied down
=IF(OR(J2="",K2=""),"",SUM(INDEX($C$2:$G$6,MATCH(J2,$B$2:$B$6,0),MATCH(K2,$C$1:$G$1,0)):INDEX($C$2:$G$6,MATCH(L2,$B$2:$B$6,0),MATCH(M2,$C$1:$G$1,0))))

Formula in N7
=SUM(N2:N6)

Remark:
The user must enter the coordinates as follows
1. a single cell
Repeat the coordinates in columns J: K and L: M
2. An area
Insert the coordinates of the leftmost cell in columns J: K; insert the coordinates of the rightmost cell in columns L: M

Hope this helps

M.

Thanks Marcelo, this is precisely what I was looking for.
