LOV Filter (Case/Value)

 Hello Community,

I’m trying to link two LOV fields, (Case type to case category)

These 2 fields are defined in basic data

I have created a custom field to reference case category in case type screen

Now in page designer I’m trying to filter the LOV

These are the steps I have followed:

1. Located both fields
2. Linked the custom field to the selector

Now what I need to do is connect the filter, can anyone please guide on this ?
