During editing parameters, it is also possible to define a conditional execution of the form's action, that is a series of conditions that must be met on the form before the action is activated. Otherwise, the deactivation of the action will occur (note - the deactivation of the action will only take place when at least once the action has been activated). After selecting the Conditional execution option, a multifunctional field will appear allowing to specify any complex condition, usually using the function.
The field has additional functionality in the form of a buton of defining simple conditions of the form process variable - operator (equal, smaller, larger, etc.) - value or other process variable.
The preview of the entered value is the same as for the parameters. It is also possible to negate introduced condition using the Negation option below the condition field.
