cannot load scene using onclick

Can anyone help explain why I cannot get my linkedscene to load on a hotspot?

I have the following actions defined for onover and onclick of my hotspot:

<action name="hotspot_setupChange_onOver">
	trace(get(linkedscene));
	txtreplace(newurl, url, '.png', '_over.png');
	set(url, get(newurl));
</action>


<action name="skin_hotspotstyle_click">
	trace(get(linkedscene));
	if(linkedscene, set(enabled,false); loadscene( get(linkedscene), null, txtadd(MERGE|,%1) , get(skin_settings.loadscene_blend) ); );
</action>

The onover action traces the linked scene name as expected, but when I click the hotspot it traces "Null" and does not load the linked scene...

If I move the "if(linkedscene, set(enabled,false); loadscene( get(linkedscene), null, txtadd(MERGE|,%1) , get(skin_settings.loadscene_blend) ); );" to the onover action the scene loads as expected.

Cheers,
Olly
