as you can initially all is zero

As I enter the value and click on submit the symbol appears with the value but it doesn't appear in total

both are field types is the currency
I am using this code for totaling
/////Monthly Take-Home Income////
$(document).ready(function(){
var hope_salary_wages= $("#hope_salary_wages").val();
var hope_salary_spouse= $("#hope_salary_spouse").val();
var hope_dividends=$("#hope_dividends").val();
var hope_pensionplan_retirement= $("#hope_pensionplan_retirement").val();
var hope_socialsecurity=$("#hope_socialsecurity").val();
var hope_interestincome=$("#hope_interestincome").val();
var hope_unemployment_foodstamps=$("#hope_unemployment_foodstamps").val();
var hope_realstate=$("#hope_realstate").val();
var hope_militarypay=$("#hope_militarypay").val();
var hope_alimony_childsupport=$("#hope_alimony_childsupport").val();
var hope_royalties_otherincome=$("#hope_royalties_otherincome").val();
hope_takehomeincome = parseInt(hope_alimony_childsupport)+
parseInt(hope_salary_wages)+parseInt(hope_salary_spouse)+parseInt(hope_dividends)+parseInt(hope_pensionplan_retirement)+parseInt(hope_socialsecurity)+parseInt(hope_interestincome)+parseInt(hope_unemployment_foodstamps)+parseInt(hope_realstate)+parseInt(hope_militarypay)+parseInt(hope_royalties_otherincome);
$("#hope_takehomeincome").val(hope_takehomeincome);
});
Any help would be great!!!
