+💻 Script Code
+// ==========================================================================
+// Script Name: Auto Priority Update based on Impact and Urgency
+// Table: Incident
+// Type: onChange | Fields: impact, urgency
+// UI Type: All
+// Version: 2025 Production Ready
+// ==========================================================================
+
+function onChange(control, oldValue, newValue, isLoading, isTemplate) {
+    // Skip execution if form is loading or field is empty
+    if (isLoading || newValue == '') {
+        return;
+    }
+
+    // Get Impact and Urgency values
+    var impact = g_form.getValue('impact');
+    var urgency = g_form.getValue('urgency');
+
+    // Define Priority Matrix (ITIL standard)
+    var priorityMatrix = {
+        '1': { '1': '1', '2': '2', '3': '3' },
+        '2': { '1': '2', '2': '3', '3': '4' },
+        '3': { '1': '3', '2': '4', '3': '5' }
+    };
+
+    // Find the new Priority
+    var newPriority = priorityMatrix[impact]?.[urgency];
+
+    // Update the Priority field if valid
+    if (newPriority) {
+        if (g_form.getValue('priority') != newPriority) {
+            g_form.setValue('priority', newPriority);
+            g_form.showFieldMsg('priority', 'Priority auto-updated based on Impact and Urgency', 'info');
+        }
+    } else {
+        // Optional: Clear Priority if invalid combination is selected
+        g_form.clearValue('priority');
+        g_form.showFieldMsg('priority', 'Invalid Impact/Urgency combination — priority cleared', 'error');
+    }
+}
+
+🧠 How It Works
+
+The script runs automatically when Impact or Urgency changes.
+It checks the ITIL-based matrix to determine the correct Priority.
+If a valid combination is found, the Priority field updates automatically.
+A small info message appears to confirm the update.
+
