$function $ #slider-range slider range true min 0 max 50000000 values 0 50000000 slide function event ui $ #amount html $ + uivalues 0 + - $ + uivalues 1 ;

To make the slider move in increments of 50000, you can add the step option to the slider configuration:

$(function() {
  $( "#slider-range" ).slider({
    range: true,
    min: 0,
    max: 50000000,
    step: 50000, // Set the step value to 50000
    values: [ 0, 50000000 ],
    slide: function( event, ui ) {
      $( "#amount" ).html( "$" + ui.values[ 0 ] + " - $" + ui.values[ 1 ] );
      $( "#min" ).val(ui.values[ 0 ]);
      $( "#max" ).val(ui.values[ 1 ]);
      $(ui.handle).attr("data-value", ui.value); // Update handle popup value

      $('#qp_has_price').attr('data_value', ui.values[ 0 ]+'to'+ui.values[ 1 ]);
      $('.qq_price_range .qq_selected_terms').html( ui.values[ 0 ]+','+ui.values[ 1 ]);

      $('.qq_clear_all_filters').prop('disabled', false);

      setQueryStringParameter('price', ui.values[ 0 ]+'to'+ui.values[ 1 ]);
      qq_call_loads();
    }
  });

  $( "#amount" ).html( "$" + $( "#slider-range" ).slider( "values", 0 ) +
   " - $" + $( "#slider-range" ).slider( "values", 1 ) );

  // Initialize handle popups with default values
  $("#slider-range .ui-slider-handle").each(function() {
    $(this).attr("data-value", $(this).slider("value"));
  });
});

With this code, the slider will move in increments of 50000 as you make selections
