what I meant was that if page2 is viewed as is, then you would get an 
error because there is no definition of var1/2 on page two, but when you 
view page1 which has page2 embedded in it, there shouldnt be any errors.

whereever you get the key error... the key error should not appear for 
page1 and on page 2 there should be an attribute error. so whereever you 
get a KEY error just include that
