Not able to filter dropdown values based on user's Location

Hi Team,

I created an onboarding front end form with one custom column field having multiple values in the drop down.

CustomProperty10:

Values:

Bulding01

Bulding02

Bulding03

Bulding04

Bulding05

Scenario:

1) When requester(from Europe region) logs in and access the onboarding form, I wanted the dropdown to have only value as 'Bulding01' and 'Bulding02', no other values.

2) When requester(from India region) logs in and access the onboarding form, I wanted the dropdown to have only value as 'Bulding03' and 'Bulding04', no other values.

I created the dropdown in CCC_Employee_Edit, tried changing the where clause of 'Permitted Value' but it doesn't work.

Could you please suggest how to achieve this scenario ?
