Displaying Field Values in TextBox

Tue, 02 Oct 2012 18:24:14 GMT

Hey Everyone-

I have this table:

Run Name	Run Date	No. of Runners
May 2011 Run	5/1/2011	1,952
June 2011 Run	6/1/2011	3,075
July 2011 Run	7/1/2011	4,724
August 2011 Run	8/1/2011	163
September 2011 Run	9/1/2011	1,977
October 2011 Run	10/1/2011	1,072
November 2011 Run	11/1/2011	1,156
January 2012 Run	1/1/2012	1,593
February 2012 Run	2/1/2012	1,070
March 2012 Run	3/1/2012	1,151
April 2012 Run	4/1/2012	1,244
May 2012 Run	5/1/2012	1,021
June 2012 Run	6/1/2012	654
July 2012 Run	7/1/2012	627
August 2012 Run	8/1/2012	483
September 2012 Run	9/1/2012	0

In order to calculate a "baseline," whatever Run Name a user selects in a list box, I have QV average the No. of Runners of the 12 *previous* Run Name(s) (and not including the selected Run Name). In otherwords, if they choose "June 2012 Run," QV averages the No. of Runners from the Run Name of May 2011 Run to May 2012 Run. Likewise, if they choose "August 2011 Run," No. of Runners will be averaged from Run Name "May 2011 Run" to "July 2011 Run."

That said, I have all of my aggregation functions working properly, however I want to *display* the Run Names contained in the baseline within a Text Box saying (in the Case of choosing "August 2011 Run"):

Baseline is calculated from the "May 2011 Run" to "July 2011 Run."

A couple of other twists:

1. The average should not exceed the 12 "Run Name." In other words, in my average calculations, if user selects "September 2012 Run" the baseline average will be from "August 2011 Run" to "August 2012 Run"

2. Notice that there is no "December 2011" run.

How do I accomplish this?

Thanks!

Assign a sequence number to the runs in order. You can do that with RecNo() during the load.

RecNo() as RunId

Then an expression like:

='Baseline is from '

& only({1<RunId={$(=RangeMax(max(RunId)-12,1))}>}[Run Name])

& ' to '

& only({1<RunId={$(=max(RunId)-1)}>}[Run Name])

Rob-

Thank you so much. This is exactly what I needed. This alone taught me a ton about RANGEMAX and ONLY. Thanks again.
