I thought I knew how to do this but it appears I dont! Setting starting values for the standard combobox plugin

I have a tour where I would like to set the default value of the combobox items with a variable when the tour starts. For example:

onload(), variable initmusic is passed into the xml from a cookie via javascript and initvars:{initmusic:initmusic...
    
<combobox name="cb_music" design="greycombo" zorder="202"  keep="true"
     x="20px" y="1999px" visible="true" align="center" edge="left"
     >
     <item name="M1" caption="auto Music ON"  onclick="set(initmusic, 'M1' );" 
/>
     <item name="M0" caption="auto Music OFF" onclick="set(initmusic, 'M0' );" />
</combobox>

Another action is used to write cookies with a varient of settings, that all works. it's only the reading and setting that are a problem.

I have tried lots of combinations based on:

  trace(get(layer[get(cb_music)].selecteditemindex;););
  trace(get(layer[cb_music].selecteditemindex;););

and seem unable to even read what is selected far less preset or setup the combobox using the (cookie) variable.

Fantastic, I never thought of putting the onload in the combobox declaration, as opposed to the item declaration. Obvious when it is laid in front of you.
