I have actually a very lengthy file of statistics however a small sample is
provided as follows:

Column B reflects Sales of different products as per column A, in year 2007
as follows:

Col - A Col - B
Product 2007
Item 1 5,000
Item 2 2,100
Item 3 800
Item 4 7,100
Item 5 8,400
Item 6 4,800
Item 7 9,700
Item 8 8,800
Item 9 2,000

while columns C:F reflect the contributions made by sales agents as follows:

Col - C Col - D Col - E Col - F
Agent 1 Agent 2 Agent 3 Agent 4
40% 10% 30% 20%
10% 40% 0% 50%
20% 40% 20% 20%
40% 20% 30% 10%
30% 20% 10% 40%
10% 30% 50% 10%
30% 50% 0% 20%
0% 40% 10% 50%
30% 0% 30% 40%

now Column G shows the sales of the year 2008, while Column H shows the
agents contributing this time as follows:

Col - G Col - H
2008 Agents
9,000 1, 2, 4
1,100 2, 3
2,100 1, 3, 4
15,600 4
15,400 1, 4
7,700 1, 2, 3, 4
18,600 3, 4
11,300 1, 2, 4
3,800 2, 4

I want a formula in Columns I:L distributing the amount of sales 2008
amongst the agents participating this time in the following format:

Col - A Col - I Col - J Col - K Col - L
Product Agent 1 Agent 2 Agent 3 Agent 4
Item 1
Item 2
Item 3
Item 4
Item 5
Item 6
Item 7
Item 8
Item 9

Where any of the agent was not found to be contributing any amount last
year, i.e. 0%, then the amount he should be denoted with an equally
proportionate amount of 2008 while the others would share the remaining
amount in their former ratio. For example, item 8's sales of 2008 of 11,300
would be divided as 3,767 (i.e. 1/3) for Agents 1 because Agent had
contributed nothing last year and this time there are 3 agents involved.
While the remaining 7,533 would be divided in the proportion of 4:5 amongst
Agents B & D, i.e. 3,348 & 4,185 repectively. Sure is a challenge but sure am
relying upon your expertise blind-folded.
