Excel中的逻辑运算符：如果不是

Question

I'm new in Excel VBA programming and I am trying to do the following within a Macro:

  If Not Sheets(Currencies).Range("B2") <> "USD" Then
    Sheets(Currencies).Range("B2").Value = "=USD"
        Call Sheet3.UpdateCurrencyList
End If

EDIT: I have fixed the codes from the comments below, but now I get runtime 9 error.

Answer 1

There are 2 errors:

1. there arent double quotes in the first row before and after Currencies
2. USD is not a formula but a value

Try this:

Sub MySub()

If Not Sheets("Currencies").Range("B2") = "USD" Then
    Sheets("Currencies").Range("B3").Value = "USD"
        Call Sheet3.UpdateCurrencyList
    Else
End If

End Sub
