Then try this:

=B2+INDEX($C$2:$X$2,ROWS($1:1))

And copy down.

Thanks Steve and Ragdyer, I feel I may have explained it wrong,
eg:

B C D E F G H
3 7 4 9
2 B2+C2 = 2+3 = 5
3 B3+D2 = 3+7 = 10
6 B4+E2 = 6+4 = 10
8 B5+F2 = 8+9 = 17

Really appreciating the help on this.

Tommy,

This should work for you.

=SUM(B5:B10+TRANSPOSE(B3:G3))

This is an array formula so commit with Ctrl-Shift-Enter.
