[TYPO3] tt_news menu and filtered news....can anybody help me???

[luca]

Hi,
I'm using tt_news for the first time and I'm having some trouble to
manage filtered views of the news.
I'm using Tv and I have mapped a leftMenu in order to display a menu
with a list of categories. This is working.

Now I would like to display in the page id=131 a list of filtered news
based on the item selected in the above menu.
I have created a couple of news and assigned them to their category

This seems easy but somehow I cannot display in my content page the list
of news selected through the above menu.

How do I have to configure the page record? I have set LIST in what to 
display....

Do I miss something?

Here it is my ts:
#############################################
lib.leftMenu=CONTENT
lib.leftMenu.table = tt_news_cat
lib.leftMenu.wrap = <ul id="LeftNavBar">|</ul>
lib.leftMenu.select {
   pidInList = 89
   orderBy = uid
}
lib.leftMenu.renderObj = COA
lib.leftMenu.renderObj.10 = TEXT
lib.leftMenu.renderObj.10.field = uid
[globalVar = GP:cat = uid]
lib.leftMenu.renderObj.10.wrap = <li class="selected"><a
href="?id=131&cat= | ">
[else]
lib.leftMenu.renderObj.10.wrap = <li><a href="?id=131&cat= | ">
[global]
lib.leftMenu.renderObj.20 = TEXT
lib.leftMenu.renderObj.20 {
field = title
wrap = | </a></li>
}
##############################################

Thank you for your help!
