请教:为什么FOR NEXT 语句运算结果为0?

想做NO.1

下列代码中,无论N为什么整数,在EXCEL和ACCESS里运行时结果都为0,请哪位帮我分析一下,
Function aa(n As Integer) As Long
Dim m As Long, i As Integer
m = 1
For i = 1 To n
m = m * i
Next
End Function

在ACCESS里面编译后,出现一条"表达式中'aa'函数未定义"的对话框,请问怎么定义函数.

谢谢啦.

没有把计算结果给aa，当然就是0。

Function aa(n As Integer) As Long
Dim m As Long, i As Integer
m = 1
For i = 1 To n
m = m * i
Next
AA=m
End Function

想做NO.1

谢谢楼上的朋友!!
这书本也害人啊.
