I have found an article on dynamic lookup list:

https://www.zoho.com/creator/help/fields/configuring-conditional-drop-downs.html#Create_Dynamic_Lookup

However, when I try this with the latest app builder, I click on the Set Filter box and it pops up with proper fields and such.  But when I type in the condition like CONTEXT_CODE equals input.Country_Lookup, when it saves, it keeps saving as CONTEXT_CODE == "input.Country_Lookup" and treat my variable name as literal constant.

In my case, I have a single form that has LOOKUP_CODE, LOOKUP_TYPE, CONTEXT_CODE to show various lookup codes.

Country_Lookup is the Field name for my Country field.  So the complete filter should be saved as the following:

((LOOKUP_CODE = "STATE_OR_PROVINCE") && (CONTEXT_CODE == input.Country_Lookup))

But the app builder keeps saving it as the following:

((LOOKUP_CODE = "STATE_OR_PROVINCE") && (CONTEXT_CODE == "input.Country_Lookup"))

So is there a new way to do dynamic Lookup list that the article that I paste in here no longer valid?

Any help will be appreciated.  Thanks.
