Excel VLOOKUP inconsistent results

Question

I am trying to make a simple gradebook using VLOOKUP in Excel for a class, but for some reason, some of my entries are getting a #N/A error while others find the correct value. Any ideas or suggestions on how I went wrong would be appreciated. Below is the formula and a link to the workbook itself.

=VLOOKUP([@GPA],J9:K21, 2, TRUE)

Answer 1

您只需要使用$ dollar符号将数据范围更改为绝对引用，至少在行号前面：

=VLOOKUP([@GPA],J$9:K$21, 2, TRUE)
