Pass an argument to a custom function

Hi all,
I have a problem when I want to pass an argument to a custom function:

for(set(i,0), i LT plugin.count, inc(i), 
 if(plugin[get(i)].state == 'on', 
  hidewindow(plugin[get(i)].name); 
 );
); 


<action name="hidewindow">
 <!--showlog();-->
 trace('Azione hidewindow: ', %1);
 set(plugin[%1].enabled,false);
 tween(plugin[%1].alpha,0);
 tween(plugin[%1].blur,20);
 tween(plugin[%1].y,-1500, 1.0);
</action>

In textfield plugin I add a custom tag "state"

Problem:
When I pass the name of textfield as hidewindow(plugin[get(i)].name); it does not work,
while if I use hidewindow(htmltext); it work fine.
htmltext,htmltext2, htmltext3 are the name of textfieldin the scene...
Because if I pass the argument as plugin[get(i)].name it does not work; there are some limitation.
If I show log in my custom function the name is correct

To test the function click "OPEN HTML"
