The code requires you to have an error pop up when if its greater than 1, less that 50?

I have to hav开发者_开发知识库e the program display an error if the term the user types is less than 50 or greater than one so anything inbetween is an error. The user must type 50+ or 0 to not get an error. I was almost positive it worked until I looked at the project closer. I get the error when you type any number.

    Const strMSG As String = "The term must be less than 1 or greater than 50."
    Const strMSG2 As String = "The term must be less than 1 or greater than 50."

    txtOwed.Text = FormatCurrency(txtRegistrants.Text * 80)
    If txtOwed.Text > 50 Then
        txtOwed.Text = txtOwed.Text
    Else
        MessageBox.Show(strMSG, "Monthly Payment Calculator", _
                        MessageBoxButtons.OK, MessageBoxIcon.Information)
    End If

    If txtOwed.Text < 1 Then
        txtOwed.Text = txtOwed.Text
    Else
        MessageBox.Show(strMSG2, "Monthly Payment Calculator", _
                        MessageBoxButtons.OK, MessageBoxIcon.Information)
    End If

Change your code to the following:

If val(txtOwed.Text) > 1 and val(txtOwed.Text) < 50 Then
  MessageBox.Show(strMSG, "Monthly Payment Calculator", _
                    MessageBoxButtons.OK, MessageBoxIcon.Information)
End If

Note that I solved for your subject line, not your enclosed verbiage and example code

I think this is the easiest for most people to understand:

If not(txtOwed.Text > 50 or txtOwed.text = 0) Then
    MessageBox.Show(strMSG, "Monthly Payment Calculator", _
                    MessageBoxButtons.OK, MessageBoxIcon.Information)
End If

but

not(txtOwed.Text > 50 or txtOwed.text = 0)

is equivalent to

(txtOwed.Text <= 50 and txtOwed.text <> 0)
