error in mapping form to case class in play 2 for scala

val registrationForm: Form[Registration]=Form(
mapping(
"fname"->text(minLength=2),
"lname"->text(minLength=1),
"userEmail"->text(minLength=5),
"userPassword" -> tuple(
    "main" -> text(minLength = 6),
    "confirm" -> text
  ).verifying(
    // Add an additional constraint: both passwords must match
    "Passwords don't match", userPassword => userPassword._1 == userPassword._2
  ),
"gender"->number,
"year"->number, 
"month"->number, 
"day"->number
)
{
// Binding: Create a User from the mapping result (ignore the second password and the 
accept field)
(fname, lname, userEmail, userPassword, gender, year, month, day, _) => 
Registration(fname,lname,userEmail,userPassword._1, gender, year,month,day)//error here
 } 
 {
  // Unbinding: Create the mapping values from an existing User value
user => Some(user.fname, user.lname, user.userEmail,(user.userPassword, ""),
user.gender, user.year, user.month, user.day, false)
}

)//end registrationForm

My case class is -

case class Registration(fname:String, lname:String, userEmail:String,
userPassword:String, gender:Int, year:Int,month:Int, day:Int )

The above code is giving a error- wrong number of parameters; expected = 8. I have giving comment to the line in which error occurs

The argument list of the apply function is too big:

(fname, lname, userEmail, userPassword, gender, year, month, day, _)

It should be 8 as your form contains 8 elements:

(fname, lname, userEmail, userPassword, gender, year, month, day)
