back ground- ive only been learning VB.net for about a week and am using a tutorial www.homeandlearn.co.uk.

i am at the tutorial about the calculator and have hit a snag- my problem is that i have to do the equals button but dont know how to

heres the sub of code

Private Sub btnEquals_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles btnEquals.Click

Total2 = Total1 + (txtDisplay.Text)
txtDisplay.Text = Total2
txtDisplay.Clear()
End Sub

i am also having trouble with the add button- here is the code for that

Private Sub btnPlus_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles btnPlus.Click

Total1 = Total1 + Val(txtDisplay.Text)
txtDisplay.Clear()
End Sub


any help would be greatly appreciated thanks in advance
