I have a table as below:

A B C D E
1 Value 2 9 5 Total
2 Item 1 x
3 Item 2 x x
4 Item 3 x
5 Item 4

Whereever x is plotted, I need the cell to be assigned values from the
corresponding row above.
Eg. Item 2 is marked x in col B, I want the cell B3 to have a value 2 even
though x can be seen. Similarly item 2 is marked x in Col D, should now have
a value 5.
I need to sum up these values in the total column E.

Do reply.
