在VBA中修复中间函数的语法错误？

Question

I'm working in VBA excel and I'm trying to write a mid function but I keep getting a syntax error and I can't figure it out.

Here's the code:

Mid=("RXOTRX", "8", "7");

If you're trying to use the VBA Mid function, then your code should look something like this:

MidValue = Mid("RXOTRX", 8, 7)

Note that in your example, the start position would be past the end of your search string "RXOTRX" so it would return a zero-length string ( "" ).
