[O] Capture Template problem

[Chao LU]

Dear All,

I found a little problem when configuring Org-Capture.

The target file is iPrv.org, whose structure is like this:
=======
* INBOX
*** A
*** B
*** C
=======
So I defined a template like :

 ("i" "INBOX" entry (file+olp (concat org-private-dir "/iPrv.org") "INBOX") "*** %?" :prepend t)

But the Results turned out to be:
=======
* INBOX
** D       ---->  What I want is *** D (Level 3, not 2)


*** A
*** B
*** C
=======

So I changed my configuration a little like:
 ("i" "INBOX" entry (file+olp (concat org-private-dir "/iPrv.org") "INBOX" "INBOX") "*** %?" :prepend t)


And accordingly the iPrv.org file.
=======
* INBOX
** INBOX
*** A
*** B
*** C
=======

But still error: Heading not found on level 2: INBOX.

I'm using org 7.5 on Emacs OSX 23.3

Thanks,

Chao
