Incrementing a number

[neomulemi6]

This should be incredibly simple, and I don't know why I can't figure it out. I want my form to count the number of times a button has been clicked. As far as I can tell, Visual Basic has no increment operator, which is really stupid.

Private Sub Form_Load()
Dim intCounter As Integer
intCounter = 0
End Sub
 
Private Sub Command1_Click()
intCounter = intCounter + 1
End Sub

I've also tried different operators that work in other programming languages, such as intCounter++ and intCounter+=1, but none of them seem to work. Why doesn't this work? It's embarrassing that I can't figure this out.
