Data Consolidation

```Biff: Thanks so much for your input on the automation. After a small
bit of tweaking, your formula worked like a charm.

Now that I have the correlation multi-year table comparison automated,
I would like to consolidate each commodities multi-year correlation
into an overall correlation set.

What I have now is five sets of correlation rows/commodity
(representing the five historical data sets) which look like the
following:

==============================
1yr:	C	S	PN	SI	SM
5yr:	BO	BP	CD	DX	EU	GC	S	SF
SM
10yr:	DX	EU	GC	MP	SF	SI	W
15yr:	DX	TU	SP	MP
20yr:	CC	GC	MP
Overall: ???

I want to create a formula which simultaneously looks across the five
rows of historical data and provides one row (Overall) of the unique
correlations for each commodity. So, for example, in the above
example, the Overall row (minus the duplicates) for AD would look as
follows:

AD Overall:  BO, BP, C, CC, CD, DX, EU, GC, MP, PN, S, SF, SI, SM, SP,
TU, W

I will probably apply a logical filter to the above where the symbol
will need to show up at least x times over the entire historical data
set for it to qualify as a solid correlation. (e.g., If DX appears in
5, 10 and 15 years but TU only appears once, DX would be considered a
strong correlation whereas TU would be weak.). So, in the end, the
overall row would be minimized to:

AD Overall:  DX, EU, GC, MP, SF, SI, SM

Any and all help would be appreciated.

Difficulty Aligning Series Data With Proper Dates
I ‘m building a column graph using Excel 2007 and I’m having difficulty aligning a series of data with the proper dates. I have 2 series of data – Series 1: Includes a value for each quarter in 2009 (e.g., Mar-09, Jun-09, etc). Series 2: Includes a value for each quarter in 2010 (e.g., Mar-10, Jun-10, etc). After creating each series, I select the appropriate dates (Series 1 – 2009 dates / Series 2 – 2010 dates). The first issue that I’m having is that when I select the second set of dates (for Series 2), it overrides the first – so the x-axis initially shows 2009 dates, but then ...

export public folder data?
Am in the process of performing an Alternate server recovery of an Exchange 2003 Information Store. The reason being that on the current server all the email has dissappeared from the public folder mail folders...its a very strange situation indeed. Hoping that by restoring an earlier backup to a different machine we can see if the emails will return. If they do, is there a way I could export the contents of these folders back into the current info store? I gather that Exmerge will only work on Mailboxes and not Public Folders...

Selecting specific data #2
Hi everyone I have another little problem. I have got a list of 20 items on sheet1, Cells A1 - A20 (numbered 1 - 20) and Cells B1 - B20 are items relating to that number, ie, number 1 = Concrete, number 2 = walls, and so on. Now on sheet 2 I have a table, again cell range A1:B20. I would like to know a formula so that when I enter a number in to column A, the corresponding item to that number appears in column B. ie, if I enter number 8 in Cell A1 on sheet 2, then I would like Floor to appear in Cell B1.

data file: how to start its application
