VBA AND Logical Operators

I'm trying to meet set criteria in b5 using AND the first works if both conditions are met in two cells but bur won't on one cell?

Private Sub PTIColours_Click()
If Range("b5") > 0 And Range("c5") < 0.149 Then
Range("a5").Interior.ColorIndex = 54
End If
End Sub

But this dosen't

Private Sub PTIColours_Click()
If Range("b5") > 0 And Range("b5") < 0.149 Then
Range("a5").Interior.ColorIndex = 54
End If
End Sub

I have tried searching for a good example of how to use logical operators on Mr Excel however the search is frustrated by "Small Words" in the search field ie IF, AND, NOT ,OR are too short to search.
