计算导致跨度崩溃

计算是制动函数我试图做一个计算但它制动我的其他函数计算很简单从另一个span中取出一个span

Jquery

 function caclulateBalance() {
          incomescic = +$('#sumTotalIncome').text();
          expensecic = +$('#expendureTotalSum').text();
          reducible = +$('#reducibleSumTotal').text();
          incomes = +$('#totalsIncomeiande').text();
          expenses = +$('#totalexpensessum').text();                     

          $('#Total').text(incomescic - expensecic + reducible ).toFixed(2);              
}

Html

Income: <strong><span id="totalbalancesum">143</span></strong>
expenses:<strong><span id="totalbalancesum">143</span></strong>
<span id="expenses" >60</span>
Reducible: <strong><span id="reducibleSumTotal">143</span></strong>
<span id="expenses" >60</span>
<span id="Total" >answer should be 23 and displayed here</span>

function caclulateBalance() {
         var incomescic = parseFloat($('#sumTotalIncome').text()),
          expensecic = parseFloat($('#expendureTotalSum').text()),
          reducible = parseFloat($('#reducibleSumTotal').text()),
          incomes = parseFloat($('#totalsIncomeiande').text()),
          expenses = parseFloat($('#totalexpensessum').text()),
          total = (incomescic - expensecic + reducible).toFixed(2);
          $('#totalbalancesum').text(total);

      }
