Two Different Scripts To Work Together?

currently working on a project involving an interactive map with various properties on it that people can find info about.

// BYPASSING THE MAP ID FOR TESTING PURPOSES - 1 REPRESENTS WINDSOR EAST
var location = 1 ;
var social_housing_type = document.getElementById('social_housing_type').value;
var layout = document.getElementById('layout').value;
