GiaP on "Contact Form 7 Range Slider Output Number"

Hi couple of questions and first, really really appreciate you posting your solution!!

1. Just a bit confused about execution:

$(".range-24").append(html);

$('#budget_range').on("change mousemove", function() {
$(this).next().html($(this).val());
});
</script>

Note the name in the code. Since my slider was named range-24 the range slider I made must also be the same name. You can change the min and max number to whatever you like. Where it says:

$(".range-24").append(html);

Where would I insert the values? I need to users to be able to choose a year using the slider. Range is from min value of 1897 to maximum value of 1996.

Thanks so so much!
