Question

我们正在使用iReport 5.0.1，并已成功转换了许多Crystal Reports包。

我正在使用整数和双数据类型混合的数据，我在详细信息部分的变量字段中执行计算。

然后我有3个变量来汇总详细数据。第一个变量是它上面的细节变量的直接和。第二个添加一个参数或第二个参数，具体取决于IF..THEN..ELSE语句，第三个根据类似的IF..THEN..ELSE语句减去相同的参数值。

我需要对Group Footer中的3个变量字段进行舍入，因此我将Math.round（variable_name）应用于3个变量中的每一个。原始的和最后一个（减去参数）都可以完美地工作。中间变量（添加参数）会抛出错误“错误评估表达式：Math.round（variable_name）”。如果我取出格式，它运行正常。

我已经复制并粘贴了工作变量，将其重命名为正确的名称，以确保我不会错过我最初设置它们的方式，但无济于事。当我使用空数据源运行它时，它会运行，但当然没有数据。

这会让我相信数据存在问题，但我已经检查了整个数据，数据对数据源都是有效的，没有NULL，空白或字符数据。

我在这一点上很难过。该报告在Crystal Reports中编译和运行得很好，使用非常接近相同的函数。

如果有人有任何建议，我很乐意倾听，我正在发布以下报告的XML。

提前感谢您提供任何帮助。
