No worries!  One way would be to declare a global variable at the top  
of each card's script that needs to access your points.   By  
convention, you would name the variable starting with a letter  
"g" (for global).  For example:

At the top of  your stack script:

global gUserPoints

Then in your on preOpenStack handler or on openStack handler:

put 0 into gUserPoints

If you store the values away somewhere when they exit and come back  
into the game, you can set a different value into your variable:

put pointsSoFar into gUserPoints

Then, at the top of each of your card scripts that need to access  
this variable again use:

global gUserPoints

So the user now does something on this card to earn 10 additional  
points:

add 10 to gUserPoints

You get the point....
