Variable sets enable you to modify values of various user-defined variables and use them in different outputs.
Default Variable Set is the master variable set. When you insert a variable, the variable is taken from Default Variable Set.
You can create different variable sets in the User Defined Variables pod to override the values of variables in Default Variable Set and use them in different outputs. To use a variable set other than Default Variable Set, select the variable set in the Content pane of layout properties.
1)Click the Add/Edit Variable Set icon.
2)Click Add and specify a name for the new variable set.
note: You can edit and delete a variable set in the Variable Set dialog box by clicking the respective buttons.
