what's wrong in the above code ? i am getting this error :

 

Parse error: syntax error, unexpected '{' in C:\AppServ\www\Voting\registration.php on line 16

 

why ?

[bluebyyou]

which one is line 16?

 

edit:

 

if (isset($_POST['nickname']) && isset($_POST['password']) && isset($_POST['cpass']) && isset($_POST['email'])) {

 

missing a ending parenthesis.
