Hello,
I need help with the following code. Would be very grateful for
comments.
I have a function called emailValid, and it is supposed to alert the
user if h/she leaves the field blank. I want to run this function
before the ComputeCost function but don't know how to go about doing
it.
Thanks in advance.
