Can't understand why my variable doesn't change

I'm building a little time > pay conversion program in VB. I'm really new
to VB and don't understand why my variable pay doesn't calculate like it
should. I plug in 5 5's as a test and get $0.
Dim total As Double = 0.0
Dim timeCounter As Integer = 0
Dim time As Integer = 0
Dim pay As Double = 0.0
While timeList.Items.Count < 5
time = timeList.Items(timeCounter)
total += time
timeCounter += 1
End While
If total >= 0 And total <= 40 Then
If total >= 0 And total <= 20 Then
pay = total * 10
ElseIf total >= 21 And total <= 30 Then
pay = total * 12
ElseIf total >= 31 And total <= 40 Then
pay = total * 15
Else
PayLabel.Text = "Error"
End If
End If
PayLabel.Text = "$" & pay
