Global Variables

By using global variables, you can write expressions (see Expressions) that you can later re-use by adding global variables to your expressions. This prevents you from having to write expressions every time you use them. 

You can manage global variables by clicking Tools > Global Variables if you are a user with a role of at least Designer. A dialogue appears that allows you to manage global variables using the following buttons:

Click this button to create a new global variable.
Click this button to edit the currently selected global variable.
Click this button to delete the currently selected global variable.

For each global variable, the following attributes can be set:

NameThe name of the global variable; this name is later used to reference global variables in expressions (see Expressions).
ValueAn expression (see Expressions) that evaluates to the value of the global variable.
