+and validates user input on the Incident form based on category, impact, and urgency — all without using a Script Include.
+
+it runs whenever the Category field value changes on the form.
+
+1.Validate form fields before saving (example: block submission if “Impact” or “Urgency” is empty).
+2.Auto-calculate “Priority” based on “Impact” and “Urgency.”
+3.Hide or show fields depending on “Category.”
+4.Dynamically filter “Assignment Group” choices based on “Department.”
+
+Uses:
+Runs when Category changes on the Incident form.
+Dynamically shows/hides the Serial Number field.
+Auto-calculates Priority purely on the client side (no server calls).
+Displays inline error messages or alerts based on user input.
+Enforces logic that prevents invalid combinations.
