Hi Bruno,
Thanks. I did find your example before, but my code is different from yours.
Please look at the following code. I want to create name1 field on page1,
name2 field on page2, but I found 2 name1 fields on both pages, and on 2nd
page name1 and name2 fields are overlapped . Could you tell me why?
Because your sample is written by somebody
who writes code without understanding what
every line means ;-)
See attachment (and adapt it wisely).
