这个表在引用的时候在实测值里面输入内容后就会出现如图所示的问题 不知道 是怎么回事  代码我研究了半天 也没有错在什么地方 实在是搞不定了 还是请狐狸爸爸帮我一下麻烦狐狸爸爸了

错误提示非常清楚，“理化厂标"没有“原”这一列。

再看看：

我看到这个了  我研究了半天还是没有搞定  这段代码 是狐爸爸您写的 我只做了一点点的修改 现在就是不能用 真是急死我了

我搞明白问题出在什么地方了  但是就是不知道 怎么改 由于我的实测有很多多表头而且分布不一样  (nm & "_" & "厂标" ) = "合格"    前面nm & "_" & "厂标" 只针对一个分列 但是我的表里面有二个甚至二个以上的分列表头 这段代码就不能管用了

请问题狐狸爸爸  这样如何更改代码

狐狸爸爸 这个代码会针对这样几种情况时行判断  首先是  N值--N值、〈N值、〉N值、≥N值、≤N值   这是现在的对N值的判断。

还有一种判断就是只针对N值   厂标里面只有数字，没有大于、小于等等的符号，当实测里面的数大于或小于厂标里面的数时用正负数体现，代码如何加进去

狐狸爸爸你写的这段代码应用起来有错误 呀
