Look up value before

I am going to be using the below code for a very un-secure password that must be entered in order for an invoice price to be changed. The code is the invoice number minus 1,111 and then times two.

I believe I have to build a seperate query where the proper pass code will be stored, is that correct? If so, how to I write that sperate query? I believe that is the "vbOKOnly" section. I'm not sure where to properly tell it to look for the correct passcode. Thanks!

BeforeUpdate event of the Price control
If Me.SomeDate <  Date() - 1 Then
    If InputBox("Enter Password" <> "some string") Then
        Cancel = True
        Msgbox "Change not allowed without valid password.",vbOKOnly
        Exit Sub
    End If
End If

This code appears to be a sample in which you need to modify for your own uses. Lets say that that invoice is held in a field called MyInvoice the code might look something like this. Thanks to a snowday!!! I can't get on my window machine to test this out, but try it and let us know.

Dim strCorrectPassword as String

strCorrectPassword = (me.MyInvoice - 1111) * 2

If Me.SomeDate <  Date() - 1 Then 'Reads in a date field on your from called "Some Date"
    If InputBox("Enter Password" <> strCorrectPassword) Then 'Compares passwords
        Cancel = True
        Msgbox "Change not allowed without valid password.",vbOKOnly
        Me.Price.Undo 'undo recent change to this field
        Exit Sub
    End If
End If 

Open in new window

Agree with TheNautican's comment
If invoce number is less than 1111 then result is negative, so use:
strCorrectPassword = Abs (me.MyInvoice - 1111) * 2
No points please -- Typo correction -

If InputBox("Enter Password") <> strCorrectPassword Then 'Compares passwords

The closing parenthesis needs to be moved to the left of the relational operator.
