the fact that .presentations stays lower case is a hint the syntax is wrong

once you set the ppt object and are refer to it, you essentially need to use
the ppt object model - which is a little different than the excel object
model (objects, properties, methods, events, etc)

google the internet for tips on how to work the PowerPoint object model - or
post to the ppt newsgroup - its been too long since I wrote vba for ppt for
me to be any help there
