im doing a project for school and i cant figure this out...
Private Sub btnCalculate_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnCalculate.Click

Dim txtTotalSales As Single
Dim txtCommissionPer As Single
txtTotalSales = CSng(txtTotalSales)
txtCommissionPer = CSng(txtCommissionPer)

'Calculate Commission
txtTotal = txtTotalSales * txtCommissionPer
'Display Commission
txtTotal.Text = FormatCurrency(txtTotal)
End Sub
