Qualifiers:Not

This will return true when its subnodes do not return true. Using not combined with the evaluate qualifier allows you to compare variables or other portions of a script.

In the below script, the not qualifier was added before the evaluate qualifier to determine if the variable #test is equal to the number "1". If it is not equal to 1, then the action (unspecified here) will be taken. Otherwise the script will continue past that action.
