Intro Image wont auto hide

I am using this code (found on the forum) for my intro image, it works and closes on click but does not close after 5 seconds if someone can see whats wrong with the code its driving me nuts!

<plugin name="introimage" keep="true" url="%SWFPATH%/skin/introimage.png" align="center" onclick="hideintroimage();" onloaded="autohideintroimage();"/>
<action name="hideintroimage">
if(plugin[introimage].enabled, set(plugin[introimage].enabled,false);tween(plugin[introimage].alpha, 0.0, 0.5, default, removeplugin(introimage)););
</action>
<action name="autohideintroimage">
if(plugin[data].introImageHasBeenPlayed==false, set(plugin[introimage].alpha,0); tween(plugin[introimage].alpha,1.0,WAIT);
delayedcall(5, hideintroimage() );
set(plugin[data].introImageHasBeenPlayed,true););
</action>

I think im missing introImageHasBeenPlayed but i have no idea what that should be

this code is in my skin btw

awesome thanks a lot!
