Minitab中的Go-No go GRR

小生在些请教大家一个问题，因用Minitab用得不熟，做计数值的GRR分析时提示以下问题：

=========================================================
Attribute agreement analysis for  Data
*ERROR* Every sample must be assessed by equal number of appraisers and equal number
              of trials within appraisers.
=========================================================

我初步估计是我的数据排列有问题，但具体不知道是那儿排错了，请各位指点一下，谢谢！
