Problem with writing a code to clear the result for TextBoxes using TextChanged

[TheZealous]

Hi All,

I am a newbie to VB. I use Visual Basic 2010. I am trying to build a basic Average Calculator Application. I can make the application calculate the average.
However, I am unable to write the code to clear the resultLabel after the user enters new input into any of the TextBoxes. Could anyone please help and point me to the right direction here? Below is my codes:

Public Class AverageCalculator

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load


End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim number1 As Integer
Dim number2 As Integer
Dim number3 As Integer
Dim total As Integer
Dim average As Integer

number1 = TextBox1.Text
number2 = TextBox2.Text
number3 = TextBox3.Text

total = number1 + number2 + number3
average = total / 3
resultLabel.Text = average

End Sub

'clear result
Private Sub TexBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged

resultLabel.clear()

End Sub

Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged
resultLabel.clear()

End Sub

Private Sub Textbox3_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox3.TextChanged
resultLabel.Clear()
End Sub

End Class

Thanks in advance!
