你的自定义函数

Private Function ss(Byval x as double,y as Integer,z as Double) as double

这里有3个参数：

Byval x as double

y as Integer

z as Double

你在调用这个函数时，必须参数的类型一一对应相同

比如：

msgbox b & "年到期活期存款利息为：" & ss(a,b,d1) & "元"

这个语句中ss(a,b,d1)，就是调用到了函数

但是，你声明的

a 为 Double

b 为 Double

d1为 Double

其中b是对应函数定义中的y的，类型不一致

对于这样的一个问题我也遇到过这样的阶段，

不过慢慢的你就会适应的，因为熟了也就记住了。还有学计算机的一定要

好好的学习英语，要尝试多看国外人写的源代码和非常好的注释。国内大部分

的都是原版国外的东西。
