How Chaining is Set
The statistics columns for Jockey Changes have specific settings. When double-clicked, they will chain to the Jockey forms showing the "* Jockey Change Performance" view. The data range will be set by argument 1. (See Using MCL Variables As View Arguments about how to pass data range.). Changing to which jockey type will be set by argument 2. Name of next jockey is set by argument 3. (Please note that column "Last Jky Chg to Any Jky:WQPL(T)" has argument 3 but no argument 2 while other statistics columns has argument 2 but no argument 3.)
Lets take "Last Jky Chg to Foreign Jky:WQPL(T)" as an example. Highlight the column on the columns list at the left hand side of the "Edit View" form. The click the [Advanced] button at the right. You will see the following form.

Arguments 1 |
Gel(HrDate()-{1},',',HrDate()-1) |
In this example {1} is 120. And HrDate() is 19/10/2011. Therefore
The Gel() function combines the items (including the ',' inserted in the middle) into "21/06/2011,18/10/2011", which confirms the data range argument standard of RaceMate.
Since the argument if passed through argument 1, you must prepare {1} to receive it. |

How to Show Races of the Statistics

Let us take double-clicking on the first row of the column "Last Jky Chg to Foreign Jky:WQPL(T)" as an example. The value shown on the row is "0,3,4,18(25) w:0% p:28%". You can verify these figures on the "*Jockey Change Performance" view of the Jockey form.
