Academy level 3 - Object reference not set to an instance of an object

Good afternoon!
Someone can help me, I’m stuck for days and I do not find the error of the exercise calculate customer’s security hash.

InvokeLoginSystem1.xaml (16.5 KB)
InvokeSendEmailError.xaml (6.6 KB)

At a time it may have values or wont so just assign the local variables for both of them
