Hi @si21 ,
You can achieve this by creating an onChange Client Script on the second reference field. Use the g_form.getValue() method to retrieve the sys_id of both reference fields, or use the g_form.getDisplayValue() method if display values are needed. Implement an if condition to check if the values of both reference fields match the desired criteria, and use g_form.setValue() to update the choice field accordingly.
If my response helped, please mark it as the accepted solution ✅ and give a thumbs up👍.
Thanks,
Anand
