Thanks for the fast response Klaus

.
I tried as you told me, but unfortunately it seems not work ...

.
Here is an example that i have tried:
"
<scene name="scene1" onstart="action(donald1)>"
...
<scene/>
<scene name="scene2" onstart="action(donald2)>"
...
<scene/>
action name="donald1">
set(delayedcallstop,false);
delayedcall(10,if(delayedcallstop==false, action(pano2) ) );
</action>
action name="donald2">
set(delayedcallstop,false);
delayedcall(10,if(delayedcallstop==false, action(pano1) ) );
</action>
<action name="pano1">
loadscene(scene1, null, MERGE,BLEND(2));
</action>
<action name="pano2">
loadscene(scene2, null, MERGE,BLEND(2));
</action>
"
...but in this way don't work....
I also tried to make a single call to action, to vary the action in various ways but it seems not work btw...
Forgive the ignorance, could you enlighten me on this?
