Go to the VB IDE, menu ToolsReferences and see if there are any missing
links in the references. If there are, uncheck them, and scroll down to find
the equivalent library, which will have a different version number, and
check that.

Dear Colleagues;

I think I came across the same problem long time ago but I do not remember
how I got away with it at that time.

In the code below. The compiler stops at --Format(DateSerial(1, i, 1).,
"mmmm")

It seems that the compiler doesn't recognize "Format", even though I
referenced "Visual Basic for Applications" library. And when I browse the
objects with the Object Browser, I can see clearly that Format is under
VBA
library.

Please tell me what to do to solve this problem.


Sub Demo1()
Dim Ops(1 To 12) As String
Dim i As Integer
Dim UserChoice As Variant
' Create an array of month names
For i = 1 To 12
Ops(i) = Format(DateSerial(1, i, 1), "mmmm")
Next i
UserChoice = GetOption(Ops, 1, "Select a month")
If UserChoice = False Then
Range("A6") = ""
Else
Range("A6") = Ops(UserChoice)
End If
End Sub
