Steve,

A stack can be closed or open. A stack can also be visible or not  
visible. So it is possible that the visible property of a stack is  
true, but if that stack is closed it will still not be "seeable".  
Conversely, a stack may be open but have its visible property set to  
false. In that case it's also not "seeable". In the case of a stack  
you might have to say something like:

if the visible of stack "substack" AND the long id is among the lines  
of the stacks then
   -- do stuff
end if

Or alternatively:

go to stack "substack"
if the visible of stack "substack" then
   -- do stuff
end if

A minor style note: since the visible property always resolves to  
true or false, the following two conditional statements are identical:

if the visible of stack "substack" is true then
if the visible of stack "substack" then

Hope this helps.

Regards,

Devin
