Write your reply.

assistant: Hi Jim,
Jim, I wasn't making a suggestion, just trying to guess how your code
was organized so as to be causing you a problem.  Your later post showed
that my guess was wrong, in fact.
Yes, precisely.
Eileen, the problem is that he doesn't see a clean way to "get there
from here" and is looking for some concrete details on how to drive the
whole process.  Here's one way, not necessarily the best . . .
Global NumberOfPlayers as Integer 'Including the dealer
Global HumanIndex as Integer
Sub DealButton_Click ()
   DealButton.Enabled = False
   Call DealTheCards (NumberOfPlayers)
   Call ComputerPlayers (1, HumanIndex - 1)
   Call EnableHumanButtons ()
End Sub
Sub ComputerPlayers (FirstPlayer as Integer, LastPlayer as Integer)
   Dim PlayerIndex as Integer
   PlayerIndex = FirstPlayer
   While PlayerIndex <= LastPlayer
      Call ComputerPlayer (PlayerIndex)
      PlayerIndex = PlayerIndex + 1
      DoEvents
   Wend
End Sub
Sub ComputerPlayer (PlayerIndex)
   Dim EndOfHand as Integer
   EndOfHand = False
   While EndOfHand = False
      Select Case PlayersNextMove (PlayerIndex)
         Case NEXTMOVE_HIT
            If DoHit (PlayerIndex) = BUSTED Then EndOfHand = True
         Case NEXTMOVE_STAY
            Call DoStay (PlayerIndex)
            EndOfHand = True
         . . . etc.
      End Select
   Wend
End Sub
Finally, for example . . .
Sub HitButton_Click ()
   If DoHit (HumanIndex) = BUSTED Then
      Call DisableHumanButtons ()
      Call ComputerPlayers (HumanIndex + 1, NumberOfPlayers)
      Call Payoffs ()
      DealButton.Enabled = True
   End If
End Sub
Hope this helps a little.  Perhaps others can suggest a cleaner
structure.
