    when doing the following operation

    <fmt:formatNumber var="totalin" value="${totalrow.Received}" />
    <fmt:formatNumber var="totalout" value="${totalrow.Sent}" />
    <fmt:formatNumber var="total" value="${totalin + totalout}" />

    i'm getting this error

    An error occurred while evaluating custom action attribute "value" with value "${totalin + totalout}": An exception occured trying to convert String "1,114" to type "java.lang.Long"

    where 1114 is the value returned to either totalin or totalout.

    its very weird. this error only crops up when one of the values to be added is > 999

    ??

    You're attempting to add two formatted strings together. numberFormat I'm guessing adds in commas for the thousands.

    When it's a value under 1000, it autmatically casts them to long and adds them together. But if it's > 999 then, it formats it to x,xxx and then tries to cast to long, which it can't, since a comma isn't a number. :)

    replace "${totalin + totalout}"
    with "${totalrow.Received + totalrow.Sent}"
