当总和有负数时的表达式则显示 0

Question

我有带表达式的文本框

=Sum(Fields!servicetotal.Value, "Service") - Sum(Fields!servicefee.Value, "Service")

得到正确的结果。

如果结果数是负数，那么我需要显示（显示）0。

你能帮帮我吗？谢谢。

=IIF(
     Sum(Fields!servicetotal.Value, "Service") - Sum(Fields!servicefee.Value, "Service")<0,
    0,
    Sum(Fields!servicetotal.Value, "Service") - Sum(Fields!servicefee.Value, "Service")
    )
