Hi All,
I have some problem programming the excel table i have to sum up a
huge list of numbers.
We have many Equipment and they will be name item 1, item 2.... (These
name are not fixed and they will be added to the table we we go
along.)

For Each equipment we have area. We are suppose to sum up all the Area
for each different type of equipment.
I figure using sumif function we can sum up all the area for each
equipmnt. But that requires me to first know what are the exact names
for each equipment.

Is there any function we can automatically list out the equipment in
sorted order.

Source :
Equipment Area
Item 1 50
Item 1 50
Item 1 50
Item 2 150
Item 2 150
Item 2 150
Item 1 50
Item 1 50
Item 1 50
Item 3 100
Item 3 100
Item 1 100
Item 3 50
Item 3 100
Item 3 100

Output :
Equipment Area
Item 1 400
Item 2 450
Item 3 450
