you function seems act on result of auto complete since .unitquantity may not have been set not other 0 unless put value in unitquantity before select auto complete. need leave function possibly add default of 1 unitquantity add function handling event unitquantity value has changed last line of inline function , should have results want.

i suggest adding following right before return false;

adding.find(".unitquantity").change(function()   {     adding.find(".totalprice").html(adding.find(".unitprice").val() * adding.find(".unitquantity").val());    });

also edit inline function following...

adding.find(".unitprice").html(data[1]); adding.find(".unitprice").val(data[1]); adding.find(".productid").val(data[2]); adding.find(".totalprice").html(data[1] * $('.unitquantity').val());

your first line setting html of unit price not val when tried retrieve .val() returned 0

also note should consider adding round 2 decimal places make sure don't end many decimals total price.

unit price:50.99

total price:2804.4500000000003
