Variable Scope & 'PUSH'

I just want to check my understanding of life of the 'args' variables in a Personas script.

If I copy an on screen variable, it is available for use within the same script and therefore I can paste the saved variable to perhaps an area of a different flavour further down my script.

If however in my main script (MS1) I copy a variable - VARA contains the value 'hello'....

... and then in the course of that script, I make a conditional choice; If Condition A PUSH Button 1 (sub-script 1); If Condition B PUSH Button 2 (SS2), etc...

.... will VARA still contain 'hello' when I try to pick it up in SS1 and SS2?

I seem to be getting inconsistent results and hence I'm getting a little confused.

Any advice much appreciated,

Thanks.

Patrick.
