1. Why This Matters

If the same user is selected for multiple approval roles, approvals lose segregation and audits become weak.

This validator blocks duplicate user selections at form submission time.

2. Where to Use in Joget

Form Builder: add this as a Custom Validator on each approver-related field.

Suitable fields: dropdown, select box, or user picker fields storing usernames.

Not for Workflow Builder or API Builder: this is pre-submission form validation.

3. Configuration You Must Set

Update these field IDs to match your form:

reviewer

authorizer

approver

Attach the same validator script to each of these fields so each selected value is checked against the other roles.
