MsgBox To Pop-up To The User With 3 Options

I want a MsgBox to pop-up to the user with 3 Options.

Option A, Option B, Cancel.

If user presses Option A GOTO 1:
If user Pressed Option B GOTO 2:

And if Cancel End Sub, not sure if this is doable, please let me know. Basically I am writing this VBA to archive files from the network drive and there are two different kinds and depending on what Option the user chooses, the Destination variable needs to take on a different value, that's why I need this, unless there is a better way to do this.

Basically so far my code is like this:

Sub Archive_GTP()

Dim Nlog As Worksheet
Dim DestinationFile, SourceFile
Dim lr As Long
Dim c As Range

Set Nlog = Worksheets("Log")..........................
