public bool SaveProfile(int userId, string bio, string region, string country, string platform, Dictionary<string, int> checkboxStatesAndValues)
{
    try
    {
        // Retrieve the user ID using the provided username

        using (MySqlConnection connection = ConnectionString.GetConnection())
        {
            connection.Open();
            string query = "INSERT INTO Profile (UserID, Bio, Region, Country, Platform, Fun, Competitive, Serious, Communication, Dedication) VALUES (@UserID, @Bio, @Region, @Country, @Platform, @Fun, @Competitive, @Serious, @Communication, @Dedication)";
            MySqlCommand cmd = new MySqlCommand(query, connection);
            cmd.Parameters.AddWithValue("@UserID", User.UserId);
            cmd.Parameters.AddWithValue("@Bio", bio);
            cmd.Parameters.AddWithValue("@Region", region);
            cmd.Parameters.AddWithValue("@Country", country);
            cmd.Parameters.AddWithValue("@Platform", platform);

            // Set checkbox values for each category
            foreach (string category in new[] { "Fun", "Competitive", "Serious", "Communication", "Dedication" })
            {
                for (int i = 1; i <= 5; i++)
                {
                    string checkboxName = $"{category}{i}";
                    string paramName = $"@{category}";

                    // Check if the checkboxName exists in checkboxStatesAndValues
                    if (checkboxStatesAndValues.ContainsKey(checkboxName))
                    {
                        // Add the parameter to the command
                        cmd.Parameters.AddWithValue(paramName,    checkboxStatesAndValues[checkboxName]);
                    }
                    else
                    {
                        // If the checkboxName does not exist, add DBNull.Value
                        cmd.Parameters.AddWithValue(paramName, DBNull.Value);
                    }
                }
            }

            int rowsAffected = cmd.ExecuteNonQuery();
            return rowsAffected > 0;
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine("An error occurred: " + ex.Message);
        return false;
    }
