Export To Word

I created a VBA code that opens Invoice template in MS Word, and populates
Data from Access to bookmarks in the template, and printed as PDF File...
When I run the code it creates the First Invoice correctly....but when I
create the second or after Access Does not insert the Invoice Delials
(items), while eveything else come autmatically, so I have to logout and
login again, but always first Invoice comes OK then after Not.

Please Help it seems that the code fails every second time it as been called.

Thanx
