How to add the slider?

Hello, there is a "slider" that works with the parameter S2, but does not affect the parameter S1
You want to add a second slider that is in the same field will change the parameter S1

At the moment looks as follows:

if(who == 's1'){ who_img = '#i1'; $('.range_start_and_end').attr('min', start); } else if(who == 's2'){ who_img = '#i2'; $('.range_start_and_end').val(start); } $(who_img).attr("src",'http://csgo.boostacc.ru/wp-content/uploads/2016/02/img/'+img+'.png'); GetPrice();

As it is now
