Field = blank in Access form

This should be so simple but yet I can't get an if then statement to work in vba for an access form. I created a button called "Correct" and when it is clicked I need code to run through the data in the split form to determine if it is correct or not. I don't have an issue if it is correct but when the field is blank the code automatically returns "incorrect" unless I write the code backwards. Like
If field1 <> "" then
field2 = "Incorrect"
else
field2 = "Correct"
end if

But I want to be able to also check numerous other answers in the field so I would like something like:

If field1 = "" or field1 = "12/31/2010" then
field2 = "Correct"
else
field2 = "Incorrect"
end if

Thank you
