        If IsNumeric(TextBox1.Text) = False Or TextBox1.Text = "" Then

            TextBox1.Focus()
        ElseIf IsNumeric(TextBox2.Text) = False Or TextBox2.Text = "" Then
            MessageBox.Show("Please enter a numeric value")
            TextBox2.Focus()
        ElseIf Val(TextBox2.Text) < Val(TextBox1.Text) Then
