New 'subtxt' action for dummies (like me): solved

I decided to give the new function 'subtxt' a go.
I couldn't make it wok until I realised that it was because of my coding skills, rather than a bug.
I've decided to post it here just in case it can be helpful to future generations

So here is the scenario:

<krpano version="1.0.8.14" onstart="action(testsubtxt, pano4);"> 
<action name="testsubtxt">	
	trace(%1);	
	subtxt(pano_number,%1,4);	
	trace(get(pano_number));
</action>

Output:
INFO: pano4
INFO:

So it returns nothing. Why? Well, it's not the first time I've made this mistake using %1 params.
Because I can trace %1 value, it makes me think it's a variable already defined, but its' not.
So to make it work I have define %1 as a variable, obviously...

<krpano version="1.0.8.14" onstart="action(testsubtxt, pano4);"> 
<action name="testsubtxt">	
	trace(%1);	
	set(%1, %1);	
	subtxt(pano_number,%1,4);	
	trace(get(pano_number));
</action>

Output:
INFO: pano4
INFO: 4

Or something like this (a bit clearer):

<krpano version="1.0.8.14" onstart="action(testsubtxt, pano4);"> 
<action name="testsubtxt">	
	trace(%1);	
	set(first_param, %1);	
	trace(first_param);	
	subtxt(pano_number, get(first_param),4);	
	trace(get(pano_number));
</action>

Output:
INFO: pano4
INFO: pano4
INFO: 4

Thank you Klauss to make Krpano xml code even more powerful. I can wait to start using the new functions to create loops!

Cheers!
