Reference cell in one TAB from another using two criteria

J

Jeff

I would like to reference a cell in TAB A based on two criteria,

Where
Named_Range_Date = A1

and

Named_Range_Hour = B3

I need to be able to copy this formula so that I can populate a new table,
any ideas?

Think your intents were not specified,
ie to do what?? where the dual criteria is met

Try something along these lines, depending on your intents ..

To Count # of instances where the criteria satisfies:
=sumproduct((Date=A1)*(Hour=B3))
Press ENTER will do

To Sum another corresp named range: ReturnCol,
where the criteria satisfies:
=sumproduct((Date=A1)*(Hour=B3),ReturnCol)
Press ENTER will do

To return values from corresp named range: ReturnCol
where the criteria satisfies:
=index(ReturnCol,match(1,(Date=A1)*(Hour=B3),0))
Above must be array-entered, ie press CTRL+SHIFT+ENTER

Notes:
ReturnCol, Date, Hour are presumed identically sized named ranges
Lookup values in A1, B3 are presumed real dates & times

Example of nested And function with If function to make 2 comparisons.

=IF(AND(Name_Range_Date=A1,Named_Range_Hour=B3),Sheet2!A3,"No Match")

If the match is true then the reference in another tab is inserted. If not
true then it inserts 'No Match'. this can be replaced with double quotes
without a space between them ("""") if you do not want to see anything if
there is no match. However, by initially using 'No Match', it helps in
testing if the formula is doing what you want.

Any named range is always absolute. In the above formula, A1, B3 and
Sheet2!A3 are relative.

The following makes all cell references absolute:-

=IF(AND(Name_Range_Date=$A$1,Named_Range_Hour=$B$3),Sheet2!$A$3,"No Match")

I included the second one because I do not know just what you need when you
say you want to copy the formula.


Hope it helps.

Both you and Max are correct I could have been a little more specific.

Tab A
Column A contains Dates -- 01/01/2007
Column A Repeats each date 24 times
Column B Contains Hours -- 00:00 -- 23:00
Column B cycles 00:00 -- 23:00 and repeats
Column A & Column B have 5000 Rows.

Column C contains the data of interest.

In TAB B I would like a formula that can pick out the value in Column C where

Column A = 02/03/2007
Column B = 03:00

I would like to set up Tab B like This.

Column A Column B Column C Column D Column E Column F Column G
Row 1 1/1/2007 1/2/2007 1/3/2007 1/4/2007 1/5/2007 1/6/2007
Row 2 00:00 1 2 3 4 5 6
Row 3 01:00 2 2 4 5 5 7
Row 4 02:00 3 2 5 6 5 8
Row 5 03:00 4 2 6 7 5 9
Row 6 04:00 5 2 7 8 5 10
Row 7 05:00 6 2 8 9 5 11
Row 8 06:00 7 2 9 10 5 12
Row 9 07:00 8 2 10 11 5 13
Row 10 08:00 9 2 11 12 5 14
Row 11 09:00 10 2 12 13 5 15
Row 12 10:00 11 2 13 14 5 16
Row 13 11:00 12 2 14 15 5 17
Row 14 12:00 13 2 15 16 5 18
Row 15 13:00 14 2 16 17 5 19
Row 16 14:00 15 2 17 18 5 20
Row 17 15:00 16 2 18 19 5 21
Row 18 16:00 17 2 19 20 5 22
Row 19 17:00 18 2 20 21 5 23
Row 20 18:00 19 2 21 22 5 24
Row 21 19:00 20 2 22 23 5 25
Row 22 20:00 21 2 23 24 5 26
Row 23 21:00 22 2 24 25 5 27
Row 24 22:00 23 2 25 26 5 28
Row 25 23:00 24 2 26 27 5 29

Think option 3 from my earlier response would apply, viz:
To return values from corresp named range: ReturnCol
where the criteria satisfies:
=index(ReturnCol,match(1,(Date=A1)*(Hour=B3),0))
Above must be array-entered, ie press CTRL+SHIFT+ENTER
Click to expand...

Here's an illustrative sample specific to your set-up:
http://www.flypicture.com/download/MTIxMTk=
Extracting based on dual criteria.xls

Note: Do not click on the link direct if you're reading this in microsoft's
webpage. Do a copy n paste of the link (inclusive the "=" at the end) into
your browser.

In the sample:
Source data is assumed in tab: A, cols A to C, from row1 down. Dates in col
A, Times in col B, desired return values in col C. Each date repeats 24
times, with a total assumed of up to 210 days (say), ie till row 5040.

In tab: B,
The 24 hr times are listed in A2:A25, with dates listed in B1 across

Place in B2, array-enter, ie confirm the formula by pressing CTRL+SHIFT+ENTER
=IF(B$1="","",INDEX(A!$C$1:$C$5040,MATCH(1,(A!$A$1:$A$5040=B$1)*(A!$B$1:$B$5040=$A2),0)))
Copy B2 across as far as required & fill down to populate.
