Error says does not exist in the current context.. windows form

private void btnSubmit_Click(object sender, EventArgs e)
{
    frmRegistration obj = new frmRegistration();
    StudentInformationClass.SetFullName = obj.FullName(txtLastName.Text, txtFirstName.Text, txtMiddleInitial.Text);
    StudentInformationClass.SetStudentNo = obj.StudentNumber(txtStudentNo.Text);
    StudentInformationClass.SetProgram = obj.cbPrograms.Text;
    StudentInformationClass.SetGender = obj.cbGender.Text;
    StudentInformationClass.SetContactNo = obj.ContactNo(txtContactNo.Text);
    StudentInformationClass.SetAge = obj.Age(txtAge.Text);
    StudentInformationClass.SetBirthday = obj.datePicker.Value.ToString("yyyy-MM-dd");
    frmConfirmation frm = new frmConfirmation();
    frm.ShowDialog();

I think you are getting values from Wrong form. in your submit method you need to read values from all Lables of confirmation form.
