Website address was redirected to awardSpace main page for me. so I could not see the error happen my self.
My first guess is that you are trying to ready a form field from the wrong id... or a line of the form field is required. Whatever line 14 is reading. from the form, you just want to make sure it is not a blank or null value.
PS. I have not written PHP for about 3 years

I am in Ruby on Rails land myself, but web apps are web apps, same errors happen.
