Ok, my confusion arose from my practice of only using include files to
contain functions that would be called by the script they are "included" in,
my history is in legacy programming in which this is what include files are
for. So far I have not used it for any code that is executed directly within
the flow of the master script. Therefore all my include statements are at
the top of the master script as opposed to having them scattered throughout
the document.
Thanks for the clarification. -Don
