Variable are in scope if they are defined on the page in question or in somewhere in the parent hierarchy of the page in question.

For example, lets say the variable we are interested in is X.

• If X is defined on this page then it is definately in scope.
• If X is not defined on this page but is defined in the page .Fit Nesse (this page's parent), then X is still in scope.
• If X is defined on .Fit Nesse .User Guide .Fit Nesse Wiki then X is not in scope because .Fit Nesse .User Guide .Fit Nesse Wiki is not a parent of this page.

All variables that have been declared using !define can be checked by adding ?variables at the end of the page's url.
For example http://myFitNesseHost/FitNesse.UserGuide.FitNesseWiki?variables will show a table with the names, their values and the pages the values are defined.
