未終了<fmt：formatNumberタグ*これは可能ですか？

Question

こんにちはすべて私が引くとフォーマットしたい2つの数字を連結するチェックのシリーズをしようとしています。これは可能なのでしょうか？タイトルに誤りがある。おかげ

 <td><fmt:formatNumber value='${' 
     <c:choose> 
     <c:when test="${columnB == 'MWS'}">'line.initialQS.quantities[0]'</c:when> 
     <c:when test="${columnB == 'SMC Unfunded'}">'line.expectedUnfundedQS.quantities[0]'</c:when> 
     <c:when test="${columnB == 'SMC Funded'}">'line.expectedFundedQS.quantities[0]'</c:when> 
     <c:when test="${columnB == 'MMC'}">'line.targetQS.quantities[0]'</c:when> 
     <c:when test="${columnB == 'Current Scenario'}">'line.currentQS.quantities[0]'</c:when> 
     <c:otherwise> 
      </c:otherwise> 
      </c:choose> 
     ' - ' 
     <c:choose> 
     <c:when test="${columnA == 'MWS'}">'line.initialQS.quantities[0]'</c:when> 
     <c:when test="${columnA == 'SMC Unfunded'}">'line.expectedUnfundedQS.quantities[0]'</c:when> 
     <c:when test="${columnA == 'SMC Funded'}">'line.expectedFundedQS.quantities[0]'</c:when> 
     <c:when test="${columnA == 'MMC'}">'line.targetQS.quantities[0]'</c:when> 
     <c:when test="${columnA == 'Current Scenario'}">'line.currentQS.quantities[0]'</c:when> 
     <c:otherwise> 
     </c:otherwise> 
     </c:choose> 
     '}' 
     type="number" maxIntegerDigits='10' minFractionDigits='0' maxFractionDigits='2' groupingUsed='true' /></td>

値の変数を定義します...それを試してみることを約イムを

<fmt:formatNumber value="${bValue - aValue}" type="number" maxIntegerDigits="10" minFractionDigits="0" maxFractionDigits="2" groupingUsed="true" />
