Duplicate record

Hi,

I create a simple report .
It has 4 columns.
I can export to excel.

I go the property of the repeating frame -> format Trigger:
   if :EXCEL = 'S' then
       Write_MyText(:NrCol1||';'||:NrCol2||';'||:NrCol3||';'||:NrCol4);
  end if;

Creates the file and data export.

But when I open the excel file I find duplicate records
that occur when changing pages in reports.

How i can resolve this case?

Regards.
