ADODB.Parameter error '800a0d5d'

I have the following stored procedure and beloow it I have a piece of the ASP file that calls it.
This is the error I get:
ADODB.Parameter error '800a0d5d'

Application uses a value of the wrong type for the current operation.

/pp/processTRequest.asp, line 62

ALTER PROCEDURE [dbo].[sp_insUserInfo]
      -- Parameters for 'tbl_user'
      @personnel_id int,
      @fname varchar(50),
      @lname varchar(50),
      @username varchar(50),
      @pwd varchar(50),
      @role_ID int,
      @email_addr varchar(70)
      
AS
      DECLARE @dte_added datetime

BEGIN
      -- SET NOCOUNT ON added to prevent extra result sets from
      -- interfering with SELECT statements.
      SET NOCOUNT ON;

      SET @dte_added = GETDATE()

      INSERT INTO tbl_user(personnel_id,fname,lname,username,pwd,role_id,email_addr,dte_added) VALUES(@personnel_id,@fname,@lname,@username,@pwd,@role_ID,@email_addr,@dte_added)

'=============================================
'Stored Procedure - sp_insUserInfo
'=============================================
    Set cmd = server.CreateObject("ADODB.Command")
    WITH cmd
      .ActiveConnection = Conn
      .CommandText = "sp_insUserInfo"
      .CommandType = adCmdStoredProc
      .Parameters(1).Value = session("pid")

      .Parameters(7).Value = session("email")        <--  Line 62
      .execute()

When I take out line 62 and comment it out of my SP, I don't get an error.
what am I doing wrong?
Thanks.
