Click on Condition in the Rule panel to modify the condition. By default, a rule’s condition is True. When the condition is True, the rule will always execute, because the condition always evaluates to true.
By default, conditions are modified through the Condition Editor.
The Condition Editor provides common options for building conditions using a set of dropdowns.
Clicking the And >> allows you to make your condition more complex.
A dropdown appears to capture additional conditions. The dropdown has a default value of And. When And is used, every line of the condition must be met in order for the rule to execute. The dropdown can be switched to Or. When Or is used, the rule executes when one or more of the lines in the condition is true.
Alternatively, conditions can be written in the Expression Editor by clicking the Expression Editor button. Expressions are covered in a separate section.
