But answer me this: if what you assume is correct, how in the heck is this variable being generated (and it is) in create_edit_passengers2.py<http://example.com/create_edit_passengers2.py>(as an <input type="text"...>) and then being reinstantiated in another script? That is, if what you say is true, I should not be able to access it through ANY script whatsoever after create_edit_passengers2.py<http://example.com/create_edit_passengers2.py>is "dead", right??? Look closely: 1) variable value generated is create_edit_passengers2.py<http://example.com/create_edit_passengers2.py> 2) create_edit_passengers2.py<http://example.com/create_edit_passengers2.py>calls create_edit_passengers3.py <http://example.com/create_edit_passengers2.py>via a <form...> and passes the value of the var thereunto. 3) theoretically! Yet for some reason I can't call it in create_edit_passengers3.py <http://example.com/create_edit_passengers2.py>but *can* call it in a script that is imported by create_edit_passengers3.py <http://example.com/create_edit_passengers2.py> Now you guys can make fun of me all you want, but until you actually READ and UNDERSTAND what I'm writing, I'm afraid I think your criticisms are ridiculous and make you look like fools. For those who don't criticize me and are trying to help but misunderstand, hey, what can I say, who misunderstand so much myself lol. TIA, beno
