Problem in calculating live changing number i cannot multiply two numbers, one is live ( changing with slider,secon script) so i need to multiply the numbers
<script>
$('#customer-worth').on('keyup', function(){
$('#lafinale-profit').text(($(this).val()*($'#closed-deals-roi-calc'.val()))); //this here is the problem. I dont know how to live update number from other script (closed-deals-roi-calc)
});
</script>
<script>
$('.fs-rangeslider_track').on('touchstart',function(e){
$('#closed-deals-roi-calc').text(((parseFloat($('#number-from-
slider').innerText)/100*8.7)).toFixed(1));
</script>
To do what you require, add an input event handler to both the text and the range slider. This event handler is what performs the calculation from the values in those controls and updates the required element in the DOM, something like this:
let updateUi = () => $('#lafinale-profit').text(($('#customer-worth').val() * $('#closed-deals-roi-calc').val()) || 0);
$('#customer-worth, #closed-deals-roi-calc').on('input', updateUi);<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.0/jquery.min.js"></script>
Customer worth: <input type="number" id="customer-worth" value="1" />
ROI calc: <input type="range" min="1" max="10" id="closed-deals-roi-calc" value="5" />
<div id="lafinale-profit"></div>
