Business rules are added by editing your form or workflow. Click the Rules editing mode in the Form/Workflow Designer header to add new business rules or edit existing ones.

frevvo provides two ways to create business rules:

Visual Rule Builder - visual wizards to help create your rule. The Visual Rule Builder provides access to the generated JavaScript in the Rule Validator for editing.
Rule Validator - canvas to type in JavaScript with tools to help form/workflow designers write and debug rules.

Create a new rule by clicking on the icon.

Your new rule is given a randomly generated name. Change the name and description to describe the rule function.
Click the Run Builder button to open the Visual Rule Builder (Click the link to find out more information about the wizard) or the Rule Code button (Click the Rule Code link for details about the Rule Validator) to enter the JavaScript directly.
Click any
icon to edit an existing rule in the Visual Rule Builder.
Use the
Action Menu to
- Collapse or expand the rule (you can also collapse/expand by clicking on the rule name or the carrot.)
- Delete
  a rule. Confirm your choice in the dialog that pops up and the rule will be immediately removed. This is an irreversible process so make sure you do not need the rule before you delete it.
- Enable
  /Disable
  the rule. Rules are enabled by default.
- Move
  a rule to reorder the list. Depending on the rule's current location your choices may be "Move up," "Move down," "Move top," and/or "Move bottom." You may also reorder rules by dragging and dropping them to another spot in the list.
Click
View All to see a read-only view of the javascript for all the rules in your form/workflow.
Click Save and Test
to test your rule without leaving the Rule Editor.
