numbers

I'm fairly new to VB.net (self taught) and was just wondering if someone out there could help me out with some code. I'm not trying to do anything to invovled, just have a textbox that takes numeric value from 1 to 10. I don't want it to take a string or any number above 10. If some types a word or character an error message will appear, telling them to enter a valid number. This is what I have, obviously it's not great as I am having problems. Thanks again to anyone who can help.

 If TxtBox.Text > 10 Then
        MessageBox.Show("Please Enter a Number from 1 to 10")
        TxtBox.Focus()
    ElseIf TxtBox.Text < 10 Then
        MessageBox.Show("Thank You, your rating was " & TxtBox.Text)
        Total = Total + 1
    ElseIf IsNumeric(TxtBox.Text) Then
        MessageBox.Show("Thank you, your rating was " & ValueTxtBox.Text)

    End If
    ValueTxtBox.Clear()
    ValueTxtBox.Focus()
