Mistake in my query, error parsing the query

There seems to be an error in my query somewhere but for the life of me I cant seem to find it, if anyone could take a look that would be appreciated. Ive tried googling to see if anyone has had the same issue but no luck yet. Sorry if its a duplicate.

    public static void InsertMake()
    {

        try
        {
            using (var conn = new SqlCeConnection(_connectionstring))
            {
                if (conn.State == ConnectionState.Closed)
                {
                    conn.Open();
                }                    
                using (var command = new SqlCeCommand(@"INSERT INTO MAKE(description,lastupdatedone,is_deleted,on_server) VALUES (@Description, @DateTime, @Is_deleted, @On_server", conn))
                {
                    command.Parameters.AddWithValue("@Description", Program.Form_mmm.textBoxMake.Text);
                    command.Parameters.AddWithValue("@DateTime", DateTime.Now);
                    command.Parameters.AddWithValue("@Is_deleted", 0);
                    command.Parameters.AddWithValue("@On_server", 0);
                    command.ExecuteNonQuery();                      
                    conn.Close();                        
                }
            }
        }
        catch (Exception e)
        {
            MessageBox.Show(e.ToString());
        }

The error message is

(0x80004005) There was an error parsing the query. [token line number = 1, token line offset = 114, token in error = @On_server]

You're missing the closing parenthesis after VALUES, but you should probably include the error message to be 100% sure that's the problem.

Try changing this line

using (var command = new SqlCeCommand(@"INSERT INTO MAKE(description,lastupdatedone,is_deleted,on_server) VALUES (@Description, @DateTime, @Is_deleted, @On_server", conn))

to this

using (var command = new SqlCeCommand(@"INSERT INTO MAKE(description,lastupdatedone,is_deleted,on_server) VALUES (@Description, @DateTime, @Is_deleted, @On_server)", conn))
