Just so we're on the smame page .... An EVENT is something defined at the Variable level (meaning on the Edit Variable page) and defines what happens when the Varible reaces a certain value.
Currently, you can define two events on a variable: > and <.
Eventually, this will be expanded to >, <, =, >=, <=, Between, In List.
The one concern i have with events is that you might end up in an infinite loop.
