Anybody knows how to validate date format in the format of `mm/dd/yyyy`.
I have tried this code but is not working.

In the userform:

```
dateCheck (txtStartDate)

```

In module:

```
Function dateCheck(dateValue As Date) As Boolean
    If CDate(dateValue) <> "mm/dd/yyyy" Then
        MsgBox "Please use the mm/dd/yyyy  date format!"
        dateCheck = True
    End If
End Function

```

Am I on the right track? Thanks!
