Use firebug or Developer tools to see the elementid, Once you have the element Id document.getElementById return your element.
perseInt() parses string and returns integer

JavaScript

var in1=document.getElementById('YourElementIdForQty').value;
var in2=document.getElementById('YourElementIdForUP').value;
var in3=(parseInt(in1)*parseInt(in2)).toFixed(2);

document.getElementById('YourElementIdFotTotal').value=in3;
var total =int3;
