Oh my stupid brain 
I still have some problem during email verification.
When I use manunal id pass input, there was no problem, but when I use csv file, the program can't find the email code. Maybe when email verification does not know the first input email address, it use random email and pass in csv file.
What do i have to do?
You should use a string variable to get the value in the csv table first.
Then use the string variable to fill the email verify action.
You can use the show variable action to test if the string variable get right value of the table.
