[TYPO3] COA wrap

[Dmitri Pisarev]

Dear typo3 users, please help me to understand TS!
I'm trying to wrap two menus with one div with the following code:
20 = COA
20.stdWrap.wrap = <div id="col2"><div id="col2_content"
class="clearfix">|</div></div>
20{
                    10 < temp.menu_left
                    20 < temp.menu_left_hotels
}

Strange enough, but it does only wrap the first child(10<temp.menu_left),
and the second one stays unwraped.

What am I doing wrong?
