Please HELP with delayedcall...

Hi, I'm making a virtual tour with 7 panos.
Each pano has its own xml file and on each pano a textfield is shown by tweening its position :

this code is in the skin.xml file included in each xml pano file :

<action name="show_infos">
tween(plugin[intro].y,0,2,easeOutQuad);
delayedcall(10,close_infos());
</action>


<action name="close_infos">
tween(plugin[intro].y,-500,2,easeOutQuad);
</action>


<plugin name="intro" url="textfield.swf" 
		keep="false"
    	origin="lefttop" 
    	width="407" 
 		y="-500" 
		background="true"
		bordercolor="0xffffff"
		roundedge="50"
		autosize="center"
    	html="data:introhtml"
    	css="data:introcss"
    	selectable="false"
		zorder="1"
		onclick="close_infos()"
		children="false"
		onhover="showtext(Masquer les infos,textfieldstyle);"
    	/>

and in each xml pano file I call the show_infos action and set the introhtml data :

<krpano version="1.0.8.14" onstart="show_infos">


<data name="introhtml">
Bla bla bla pano 1
</data>

the problem is that is I load a new pano (so a new xml file calling show_infos onstart) before the delayedcall of the first one is finished the delayedcall value stays for the second one and the close_infos is called then.
Am I clear ? for exemple I start the tour with pano1.xml, it calls "show_infos()" and after 10 seconds calls "close_infos()", is I load pano2 7 seconds after the first one the "close_infos()" is called 3 seconds after pano2 is loaded instead of 10 seconds...

Is there a solution ???

Many many thanx !
