This is the case of finding someone else online. Then, the problem occurs.

A lot of problems were reported:

ReferenceError: "count" is not defined indicates that my count is not defined. Isn't it clearly defined.

I searched the internet and then said:

Instead of defining count in the script of the line details, defining count cannot use var.
Define count = 0 in onprepare of the table;

It seems that the definition of the script in the table is the same in the details, and then it can be trimmed.
