I have 5 drop down menues.
select name are auditorium1,auditorium2,auditorium3
auditorium4 auditorium5

I want to check the validation.

if I select the same number from 5 drop down menues, I will say " you have already selected this number"

And after I click "alert" sign, then the current page sends to the post page.
I do not want to send the current page to post page until there is no error.

Would you please give any idea??

Thank you in advance
