jQuery slider with input value on drag after refresh

Question

I've found this grate slider which is combo of 4 sliders sharing 100% value. Problem is that it doesn't pick value of input, yet it resets to 25% for each slider every time page is refreshed. Can someone help by making slider picking value of inputs before they determine position of slider knob.

HTML

<div align="center" class="title">Statistiche:</div>
<div id="outer_container">
<div id="container">
<span class='multislider'>Hokuto ShinKen (<input type='text' required name='question_3' class='amount' value='5' data-min='0' data-max='100'/>)
<div class='slider tied'>
</div>
Nanto (<input type='text' required name='question_3' class='amount' value='15' data-min='0' data-max='100'/>)
<div class='slider tied'>
</div>

There are two issues, var val = input.data('answer'); is wrong, there is no such data value what you need is to get the input value like this:

var val = input.val(); val = (val) ? val : 0;

and also use that value in create method instead of initValue there is no need for if condition you only need whatever is in the else clause:

$(this).slider('value', val); $(this).prev('.amount').val(val);
