"IF" statement isn't reading binaries properly

[huntrashmi]

Hello, I'm writing an "IF" statement that checks two binaries for me. It is written as such:

If Range("L70").Value = 1 Then
Range("K37") = "Pass"
ElseIf Range("B70").Value = 1 And Range("L70").Value = 0 Then
Range("K37") = "Fail"
Else: Range("K37") = "DNP"
End If

However, despite L70's value being 0, it still changes K37 to "Pass." What am I writing wrong in this statement?
