scripts to do calculation in report output PDF/HTML

[ssikji]

Hi,
Here is the example
A              B             C                  D
-----------------------------------------------------------
100                       =A1-B1          =C1/A1
400                       =A2-B2            =C2/A2
                             =A3-B3            =C3/A3
Requirement is user will insert the values in the B columns once the report is generated to PDF/HTML and delivered to them, so that in the 'C' & 'D' column they can see the dynamic values.

Any one please help me on the scripts to apply in report studio reports . I am using cognos 10.2.2 version.
Advance thanks!!

I don't believe that can be done. The output from the report will be static...
