How to get Values from Custom with Label Variable ? How to set limit of values and restrict submit

[S Deva]

There is a variable Custom with Lable for selecting multiple change requests. It should have at least 3 values before the submit form. 

I have added script : 

var Changes = g_form.getvalue("field_name").toString().split(',');

var changes_length = Changes.length;

if(changes_length>=3){

return true;

}

return false;

But this is always return false . How to achieve this can anyone please help ?
