Issue in PDDocInsertPages

Hi,

We are adding PDF pages from one docment to aother document by using below acrobat plugin API:

First PDF(pdDocFirst):
No of pages: 1

Second PDF(pdDocSecond)
No of pages: 10

PDDocInsertPages(pdDocFirst ,0 ,pdDocSecond ,5 ,1 ,PDInsertAll ,NULL,NULL,NULL,NULL);

But it adding all 10 pages instead of one page.
