error:are you missing using directive or a assembly reference?

I'm new to visual c#(window forms). I'm working on a project which consists of three forms. From1 accesses form2 and form3.Form2 worked well and good. But Form3 is giving some problem. I created form3, added three picture boxes to it and accessed from form1. Now if I run the code I'm getting the error

Error 3 'gp.Form1' does not contain a definition for 'label1_Click' and no extension method 'label1_Click' accepting a first argument of type 'gp.Form1' could be found (are you missing a using directive or an assembly reference?)

error is pointed in form1.designer.cs at this line,

this.label1.Click += new System.EventHandler(this.label1_Click);

without form3 no errors. when i add form3 im getting these kind of errors. though form3.designer is existing why its pointing to form1.designer?

namespace gp
{
    public partial class Form3 : Form
    {
        public Form3()
        {
            InitializeComponent();
        }

        private void Form3_Load(object sender, EventArgs e)
        {

        }

        private void pictureBox1_Click(object sender, EventArgs e)
        {

        }

        private void pictureBox3_Click(object sender, EventArgs e)
        {

        }

        private void pictureBox2_Click(object sender, EventArgs e)
        {

        }
    }
}

and the in form1 im accessing form3 as

Form3 frm3 = new Form3(name);
frm3.Show();

in form2 i got similar problem.i solved it by changing the name of namespace but its not working with form3. Anyone knows the answer let me know.

Add this to Form3 and see if it works:

    private void label1_Click(object sender, EventArgs e)
    {

    }

You double clicked the Label and it added an event for Click, which you probably deleted from code behind at some point
