Help with number template sensor

Configuration
1

PURPOSE / GOAL:
To detect when either adult/parent is in the basement, which contains the family room and the office. Each room has a bluetooth proxy sensor (ESPresence). The basement is where the liquor cabinets are. I want to arm surveillance cameras directed at the bar cabinets only when there is not an adult in the basement (i.e. count = 0).

PROBLEM / ISSUE:
As the template is currently written (see below), it only counts / senses the “Office”, not the “Family Room”.

CURRENT TEMPLATE:

{{ ['input_select.alex_bt_presence',
    'input_select.bluetooth_presence_courtney']
   |map('states')
   |select('eq', 'Office' or 'Family Room')
   |list|count }}
2 
{{ ['input_select.alex_bt_presence', 
'input_select.bluetooth_presence_courtney']
| map('states') | select('in', ['Office', 'Family Room'])
| list | count }}
