My If Else Statement VB.Net's weird behavior - vb.net

Question

I have this program that when I typed the same text on the form and to the other form will add one (+1) to the label of my last form..There were no errors but when I wrote the correct answers on the textboxes it just gave me a number 1 instead of 10. Please help me guys. Thanks in advance :)
here is my code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
frm4 = New Form4()
frm1 = New Form1()
Dim Textbox1 As New TextBox
Dim Label3 As New Label
If Textbox1.Text = frm1.TextBox2.Text Then
frm4.Label3.Text = (frm4.Label3.Text) + 1
If TextBox2.Text = frm1.TextBox4.Text Then
frm4.Label3.Text = (frm4.Label3.Text) + 1
If TextBox3.Text = frm1.TextBox6.Text Then
frm4.Label3.Text = (frm4.Label3.Text) + 1
If TextBox4.Text = frm1.TextBox8.Text Then
frm4.Label3.Text = (frm4.Label3.Text) + 1
If TextBox5.Text = frm1.TextBox10.Text Then
frm4.Label3.Text = (frm4.Label3.Text) + 1
If TextBox6.Text = frm1.TextBox12.Text Then
frm4.Label3.Text = (frm4.Label3.Text) + 1
If TextBox7.Text = frm1.TextBox14.Text Then
frm4.Label3.Text = (frm4.Label3.Text) + 1
If TextBox8.Text = frm1.TextBox16.Text Then
frm4.Label3.Text = (frm4.Label3.Text) + 1
If TextBox9.Text = frm1.TextBox18.Text Then
frm4.Label3.Text = (frm4.Label3.Text) + 1
If TextBox10.Text = frm1.TextBox20.Text Then
frm4.Label3.Text = (frm4.Label3.Text) + 1
End If
End If
End If
End If
End If
End If
End If
End If
End If
frm4.Show()
Else
frm4.Label3.Text = frm4.Label3.Text
frm4.Show()
End If
End Sub
Form 2 codes:

Me.Controls.Add(lbl)

Public Sub New(ByVal callerInstance As Form1)
' Call required if you add your constructor manually

' save the instance of the Me variable passed to this constructor
frm1 = callerInstance

' Dim Label21 As Label = New Label ' this label is not needed'
' Dim Textbox1 As TextBox = New TextBox ' this textbox is not needed'
' Create a new instance of Form3, do not use the automatic Form3 instance
' automatically created by VB.NET

' now you are referring to the caller instance of Form1 '
' where there is the textbox filled with your text '
frm3.Label21.Text = frm1.TextBox1.Text
frm3.Label22.Text = frm1.TextBox3.Text
frm3.Label23.Text = frm1.TextBox5.Text

Answer 1

If you want show in label number of right answers then
You need compare all user answers with right answers
And count times when answers are same:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
frm4 = New Form4()
frm1 = New Form1()
Dim Textbox1 As New TextBox
Dim Label3 As New Label
Dim sameQnt As Int32 = 0
If Textbox1.Text = frm1.TextBox2.Text Then sameQnt += 1
If Textbox2.Text = frm1.TextBox4.Text Then sameQnt += 1
If Textbox3.Text = frm1.TextBox6.Text Then sameQnt += 1
If Textbox4.Text = frm1.TextBox8.Text Then sameQnt += 1
If Textbox5.Text = frm1.TextBox10.Text Then sameQnt += 1
If Textbox6.Text = frm1.TextBox12.Text Then sameQnt += 1
If Textbox7.Text = frm1.TextBox14.Text Then sameQnt += 1
If Textbox8.Text = frm1.TextBox16.Text Then sameQnt += 1
If Textbox9.Text = frm1.TextBox18.Text Then sameQnt += 1
If Textbox10.Text = frm1.TextBox20.Text Then sameQnt += 1
'Print reslut
frm4.Label3.Text = sameQnt.ToString()
frm4.Show()
End Sub

Here is my new answer
Public Class MainForm '<----Your main form class name
Dim frm4 = New Form4()'<----declare it here
Dim frm1 = New Form1()'<----declare it here

Dim i As Integer = 0
If Textbox1.Text = frm1.TextBox2.Text Then i += 1 'frm4.Label3.Text = (frm4.Label3.Text) + 1
If TextBox2.Text = frm1.TextBox4.Text Then i += 1 'frm4.Label3.Text = (frm4.Label3.Text) + 1
