Thank you Ryan for the quick response.

So if I understand, the scope of a variable (unless Global or Namespace)is only within the page "stack".

So if I want to find the original set of a var it has to be in the hierarchy of pages?

How do I know the var e.g. @header_stuff@ is not a var set somewhere else as a Global?

Thanks.

Don

Typically, you do not have to look through the hierarchy of pages. If you are requesting /foo just override the master template value with a property tag in foo.tcl/adp.

The global value would only be used in your adp if it was the last value set, just like any other variable.

Here is another good reference:
