When creating an event the page crashes when not inputing required fields

It should instead redirect with an error saying "missing required fields" and then maybe specifying those. There should already be code elsewhere that does this so look around and try doing something that is not allowed, like destroying a key object that is already rented out :P

Hope someone has a fun time with this issue, I think it is an easy fix.
