Code for 2010 not working in 2013

[leskoms]

I am typing the following code in vba access 2013:

If (IsNull(DLookup("Username", "tblUser", "Username ='" & Me.txtUsername.Value & "'"))) Or
(IsNull(DLookup("Password", "tblUser", "Password ='" & Me.txtPassword.Value & "'"))) Then
MsgBox "Username or Password is Incorrect"

But it is not taking it, however this statement works perfectly in access 2010. It appears that it is not taking "Or" as an operator. What can I do?

Does any code run? If not, when you installed the new version, did you declare the folder holding the file as 'Trusted?'

I am recreating the database using the same codes, but in 2013 version. All of the other codes are recognized, it seems like this is the only part that doesnt want to take

Are you getting any error messages??

If so, what is the error message?

....appears that it is not taking "Or" as an operator....

So if you create two If Then Statements, one for each DLookup, the code works?
