Her code checks if new email address is not equal to old email address and should send an email in that case. But old email address is blank and in Oracle any comparison where one of the fields is null - whether it's equals, not equals, greater than, whatever - always evaluates to false. So in this case the email is not sent.

While typing this she interrupted me again to find out how to fix it (again, this is something she has to do a lot yet she cannot form a mental model of a check involving a null that allows her to solve it herself). I had to explain it EIGHT times in slightly different words until she finally grasped it.

Or at least stopped saying stupid things. I am not confident.
