Hi Glen,

Thank you for your reply, however it is beyond my comprehension.  I did
submit a reply yesterday but it is not posted.  Therefore I 'm repeating my
plead for help once more.

I have very limited PP knowledge. Recently I took a PP 2003 online course,
using PP2002 without any VBA.  I was following my course notes to learn how
to change color scheme for a presentation by creating a color-changing macro,
and then assign that macro to an action button.

I started with a new blank presentation > select an olive green color scheme
(color1) & close the task pane > record a new macro (color2) for a light
brown color scheme > change to the new color scheme & close the task pane >
click 'stop recording' on floating macro toolbar.  Likewise I created a
Color1 Macro and test ran both macros.  Both changed color scheme
successfully.

Then in master slide, I created 2 buttons and linked them to corresponding
macros, then tested them in slide show view.  Both buttons did not change
color scheme.  I don't understand why these successfully tested macros would
not work after they are linked.  I describe my steps in detail and recopy
both macros below, hoping you could figure out my mistake.

Color1 Macro

Sub Color2()
'
' light brown color scheme
' Macro recorded 11/5/2006
'

   ActiveWindow.Selection.SlideRange.ColorScheme =
ActivePresentation.ColorSchemes(Index:=12)
   Application.CommandBars("Task Pane").Visible = False
End Sub
------------------------------------------------------------------------
Sub Color1()
'
' olive green
' Macro recorded 11/5/2006 by Sung
'

   ActiveWindow.Selection.SlideRange.ColorScheme =
ActivePresentation.ColorSchemes(Index:=10)
   Application.CommandBars("Task Pane").Visible = False
End Sub
