Read the specification. These questions are easily answered there. In short, use the "varStatus" attribute.

The problem is, I don't know how to reference the current iterator. For example, how would I do something like this: int[] a = {0,1,2,3,4,5,6,7,8,9}; int[] b = {9,8,7,6,5,4,3,2,1,0}; for(int i = 0; i < a.length; i++){ System.out.println(b[i]-a[i]); } How could I achieve that in JSTL using el? <c:forEach var="total" items="${dailyTotals}"> <td> <c:out value="${total-(value in another collection with the same index as this loop)}"/> </td> </c:forEach> --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
