Crosstab with a twist

Question

Hi,
Say I have a crosstab with 3 Columns, Jan08, Feb 08, and Mar08 and two rows for Employee X.  One row displays Sum of Sales while the other displays Sum of Commissions.
Here's what I want to do:
If the Sum of Sales is below zero then make Sum of Commissons field RED otherwise DefaultAttribute OR
if the previous month's Sum of Sales was below zero, make this month's Sum of Commissions field RED as well.  So take this scenario for example
                               Jan08       Feb08     Mar08
Employee X   
Sum of Sales            -20            10            30
Sum of Commisson       15             35            40
I want the values 15 and 35 to be RED in this example.
Yesterday, I learned how to figure out the first part of my logic:  (if the Sum of Sales is below zero then make Sum of Commissions field RED otherwise DefaultAttribute)  Here's the logic for that
In Sum of Sales Suppress X+2 Conditional Formula add this:
whileprintingrecords;
numbervar i;
i:=currentfieldvalue;
false
Now you have the sum of sales in the variable i; so right click on the sum of commision field and go to font color and write this
whileprintingrecords;
numbervar i;
if i<0 then
crred
else
defaultattribute
So, how can I accomodate the second part of the OR clause?, namely:
OR
if the previous month's Sum of Sales was below zero, make this month's Sum of Commissions field RED as well.
Thank you in advance,
Zack H.

Answer 1

Raghavendra,
I'm almost there I can taste it.
So here's what I've done so far.
I created a formula called {@Setting x} and placed it in the Report Header.
Whileprintingrecords;
global numbervar x;
x:=1;
I created a formula  called {@Store Array Values} and placed it in details section (its a summarized table so detail section is fine, stores right results);
whileprintingrecords;
global numbervar array arr;
global numbervar x;
redim preserve arr[1000];
arr[x]:={Table.Value};
x:=x+1;
In the Crosstab's format field -> Font tab -> the conditional formula now looks like this.
whileprintingrecords;
global numbervar i;
global numbervar array arr;
if i<0 or arr[6]<0 then
crRed else
DefaultAttribute
I just inserted 6 as that is the row that has a negative Sum of Sales.  This actually turned all the Sum of Commissions row RED.  Obviously I am missing the step where I need to have the array dynamically change as each crosstab column changes so I don't have to hard-code the 6 (as shown in this example).  Any ideas?
Thanks again,
Zack H.
