I am Working on my project, And frustrated to solve this error. " Procedure or function uspSetSubscriptions has too many arguments specified". If any one knows please help.

protected void BtnSubscribe_Click(object sender, EventArgs e)
    {
        //Response.Write(AppUserID); 
        //Response.Write(Convert.ToString(ViewState["packtype"]));
        //Response.Write(DDConstituency.SelectedValue);
        try
        {
            db1.sqlcmd = new SqlCommand("uspSetSubscriptions");
            using (SqlDataAdapter sda = new SqlDataAdapter())
            {
db1.sqlcmd.CommandType = CommandType.StoredProcedure;
db1.sqlcmd.Parameters.Clear();
db1.sqlcmd.Parameters.AddWithValue("@UserID", Convert.ToInt32(AppUserID));
db1.sqlcmd.Parameters.AddWithValue("@packageType", Convert.ToString(ViewState["packtype"]));
db1.sqlcmd.Parameters.AddWithValue("@Cost", Convert.ToDouble(ViewState["packagecost"]));
db1.sqlcmd.Parameters.AddWithValue("@MaxNotific", Convert.ToInt32(ViewState["mxnotificaton"]));
db1.sqlcmd.Parameters.AddWithValue("@MaxVideos", Convert.ToInt32(ViewState["mxvidoes"]));
db1.sqlcmd.Parameters.AddWithValue("@MaxArticles", Convert.ToInt32(ViewState["mxarticles"]));
db1.sqlcmd.Parameters.AddWithValue("@MaxEvent", Convert.ToInt32(ViewState["mxevents"]));
db1.sqlcmd.Parameters.AddWithValue("@MaxAllias", Convert.ToInt32(ViewState["mxallias"]));
db1.sqlcmd.Parameters.AddWithValue("@ConstID", Convert.ToInt32(DDConstituency.SelectedValue));
db1.sqlcmd.Parameters.Add("@Identity", SqlDbType.Int);
db1.sqlcmd.Parameters["@Identity"].Direction = ParameterDirection.Output;
db1.sqlcmd.Connection = db1.sqlcon;
db1.sqlcon.Open();
db1.sqlcmd.ExecuteNonQuery();
Subscripid = Convert.ToInt32(db1.sqlcmd.Parameters["@Identity"].Value);
ViewState["Subscripid"] = Subscripid; 
            }
        }
        catch (Exception ex){   Response.Write(ex.Message); }
        finally {db1.sqlcon.Close(); }
    }
