Expects parameter which was not supplied....need help....

I wanted to add new record into two different tables. By using one web form...
Not so sure I coded it correctly. And I got this error trying to insert new record

" Procedure 'sp_insert' expects parameter '@.mid', which was not supplied. "

Isn't it i have include @.mid in my code ...??

<STORED PROCEDURES>
sp_insert

(
@.mid char(10),
@.status char(10),
@.name char(20),
@.dj char(20),
@.rank char(20),
@.nric char(14),
@.dob char(20),
@.age char(10),
@.add char(80),
@.school char(50),
@.hp char(10),
@.mp char(10),
@.email char(30),
@.pgname char(20),
@.relationship char(20),
@.contact char(10)

)
AS
insert into Table1(mid,status,name,date_joined,rank,nric,dob,age,address,school,house_phone,Mobile_phone,email,[P/G_name],[P/G_relationship],[P/G_contacts])
values (@.mid,@.status,@.name,@.dj,@.rank,@.nric,@.dob,@.age,@.add,@.school,@.hp,@.mp,@.email,@.pgname,@.relationship,@.contact)

insert into Table2 (name) values (@.name)

RETURN

<WEB FORM>
mycommand = New SqlCommand("sp_insert", mycon)
mycommand.CommandType = CommandType.StoredProcedure

Dim midpar As New SqlParameter("@.mid", SqlDbType.Char, 10)
midpar.Direction = ParameterDirection.Input
midpar.Value = Tb1.Text

Dim statuspar As New SqlParameter("@.status", SqlDbType.Char, 10)
statuspar.Direction = ParameterDirection.Input
statuspar.Value = ddl1.SelectedItem.Text

---Your webform code is wrong, needs to be something like this:

Dim sqlPar As SqlParameter= myCommand.Parameter.Add("@.mid", SqlDbType.Char, 10)
sqlPar.Direction = ParameterDirection.Input
sqlPar.Value = Tb1.Text
sqlPar = myCommand.Parameter.Add("@.status", SqlDbType.Char, 10)
sqlPar.Direction = ParameterDirection.Input
sqlPar.Value = ddl1.SelectedItem.Text

etc.
