Textbox inaccessible due to its protection level

Question

Class coursework asked us to create a simple energy bill. an ID number is generated on the 1st from that I want to copy to the 2nd form however I keep getting the following : Error CS0122 'Form1.idgen' is inaccessible due to its protection level
Since I'm going to referencing a lot of values from the 1st Form I just want to learn what the issue is and how to overcome it for future use This is the code for Form1:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Bill_Generator
{
    public partial class Form1 : Form
    {

        public Form1()
        {
            InitializeComponent();
            timer1.Enabled = true;

            Random r = new Random();
            var x = r.Next(0, 1000000);
            string v = x.ToString("000");
            idgen.Text = v;

        }

        public void Timer1_Tick(object sender, EventArgs e)
        {
            date.Text = DateTime.Now.ToString("dddd , MMM dd yyyy  hh:mm:ss");
        }


        public void Gen_button_Click(object sender, EventArgs e)
        {
            Form2 openform = new Form2();
            openform.Show();
        }

        public void Calc_Click(object sender, EventArgs e)
        {
            double preamt = Convert.ToDouble(prebox.Text);
            double curramt = Convert.ToDouble(currbox.Text);
            double billamt = curramt - preamt;
            billbox.Text = Convert.ToString(billamt);
        }
    }
}

This is the code so far for Form2:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Bill_Generator
{
    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
            System.Windows.Forms.Form f = System.Windows.Forms.Application.OpenForms["Form1"];
            iddisp.Text = ((Form1)f).idgen.Text();

        }

        private void Form2_Load(object sender, EventArgs e)
        {
            date.Text = DateTime.Now.ToString("dddd , MMM dd yyyy  hh:mm:ss");

        }
    }
}

You can change accessibility. However, see these Q&A: https://stackoverflow.com/questions/8566/best-way-to-access-a-control-on-another-form-in-windows-forms, https://stackoverflow.com/questions/1665533/communicate-between-two-windows-forms-in-c-sharp. Changing the accessibility is really the last resort, and should never be needed. — Peter Duniho, May 14 '20 at 00:49

by default form controls are private. In the designer UI choose the control and in its properties change the access level to public.

Changed the access and the error changed Error CS1955 Non-invocable member 'TextBox.Text' cannot be used like a method – Whitti1 May 14 '20 at 00:45
idgen.Text not idgen.Text() – pm100 May 14 '20 at 18:02
