我有一个简单的表格。我正在处理六个不同的数字范围，例如 0-1.57、1.57-6.35、6.35-12.7 等。
根据所选的类别 A、B、C 等，它会为每个范围返回不同的公差。每个类别的公差都在单独的列表中。
它的工作原理如下：“如果（选择了这个和这个），则使用此列表，否则，如果（选择了这个和这个），则使用另一个列表。
我的第一个范围正常工作，准确地从列表中提取数字。第二类的五个范围可以正常工作，但该类中的最后一个范围不会返回正确的容差。当它应该从 5 号位置抓取它时，它不断地抓取 4 号位置的公差。
这没什么奇怪的，我相信你会看到更好的方法来做到这一点，但我只是想学习不同的东西。
最后十一行粗体是未返回正确结果的行。它不断返回 B 类列表中 [4] 的结果，而不是数字 [5]，但是，A 类列表工作正常。

这种情况对我来说看起来很奇怪

你肯定想要一个
<= if (Diameter > 1.57 || Diameter <= 6.35)
