剪辑中的专家系统不起作用

Question

在我的专家系统中，用户必须在看到适合此参数的笔记本后检查开发者和价格。

例如使用此参数（在屏幕截图上）我必须有结果：Model：Noteebok1

但我什么也看不见。问题或错误在哪里？

CLP文件代码：

(defglobal ?*s* = 0)
(deftemplate Notebook
(slot pModel)
(slot pDeveloper)
(slot pPrice))

(while (not (member ?Answer ?variations)) do
(printout t ?TextQuestion)
(bind ?Answer (read))
(if (lexemep ?Answer) 
then (bind ?Answer (lowcase ?Answer))))
