Script error "Unable to find object" on object that is defined but not used.

Thanks!  The function thing worked.  Though it would be nice for there to be some way to set Aliases dynamically in scripts (especially for those of us coming from a framework like Watir who are used to setting up EVERYTHING in scripts), something like:

Aliases.add("alias_variable_name", "page.ect.ect.elementDefinition");
