[TYPO3] target in tt_news

[Thomas Hartwig]

I have an new installation of Typo3 4.0 and tt_news 2.3.4.
The installation I have made like the documentation.
The news list is shown.
I have build a project with frames.
The content frame is called "content".
In Constants I have defined:

content.pageFrameObj = content
PAGE_TARGET = content
plugin.tt_news {
   pageTypoLink.target = _top
   itemLinkTarget = content
   singlePid = 25
}

Nothing works. The click on "more" shows the whole page in content frame 
  and the message "no news_id given".

What did I wrong?
Can anyone help me?

Sincerely,

Thomas
