I have an array of data in a 2 dimisional matrix

X = date value
Y = Individual contributor

In the Matix I have plotted the expected amount of work left by an
individual on a specific date.

I would like to create a formula that can look at the date value in row 2
and return the correct value for the individual contributor on that specific
date.

Any Ideas

Assume dates are entered in B1:F1 and individuals in A2:A10 so that the
work remaining is in B2:F10. If X and Y are the values you want to
find:

= INDEX(MATCH(Y,A2:A10,0),MATCH(X,B1:F1,0))

MATCH finds the position of each value in each ray (0 means match
exactly, see help for other options)

INDEX finds the intersection of the two positions.

Hope that helps

Jeff,
I assume your date and contributor lookup values are in K1 and L1
respectively. I further assume that your table occupies the range
A2:F10 and that date headings appear in row 2 as you indicate in your
post. Change as necessary.

=VLOOKUP(L1, A2:F10, MATCH(K1, A2:F2, 0), 0)

So I would like to update the second column (avaliable) with the data from
the date columns automatically on a give day. In this instance on 12/5 the
avalible column should be A=25, B=37, C=44, D=39, E=35,F= 22

on 12/6 the values should auto update to A=24, B=36, C=42, D=38, E=34,F= 21


Redmond
Test Available 12/3 12/4 12/5 12/6 12/7
A 22 12% 38 25 25 24 23
B 33 19% 58 39 37 36 35
C 39 22% 67 45 44 42 40
D 35 19% 60 40 39 38 36
E 31 17% 54 36 35 34 32
F 19 11% 34 23 22 21 20
Goal 179 309.96 208.46 201.21 193.96 186.71

I don't see where the automatic update feature would factor into your
equation. I Probably didn't explain myself very well.

I think I see where you are going. Let's try this.
Assume the word "Available" is in cell B2. Move it to B1 and put the
date 12/7 in B2. In cell B3 enter the formula,

index(E3:H3,1,MATCH($B$2, $E$2:$H$2))

Copy this formula down and you should be good to go.

I think I am doing a terrible job of explaining what I am trying to accomplish.

Let me give a little back ground.

A) I have five developers, at the begining of a project they gave me an
estimate of the amount of time they could each devote to the project. On the
last day of the project there would be 0 avalible hours left.

B) Based on this data and the duration of the project I then calculated the
amount of avalible work left per developer per day.

C) Since I have calculated the amount of work avalible per dev per day in
the array I would like to come up with a formula that would update the
available column each day with the already calculated value for each Dev. I
am making the assumption that somewhere I will need to use the Today()
function to trigger which value gets placed in the avalible column.
