Platform: WinXP / Access 2k

Can someone assist me in a script that would be part of access and will do the following:
1) Press 1st button on a form that will create a folder based on a field entry on that form
---ie: field name [clientname] with entry in the field as "Smith, John Doe (8/14/06)"
a) If the folder already exists either give a warn message that it already exists
b) Gives the option to cancel this routine (creating the folder), and open the folder.

2) Press 2nd button on a form that will open a folder based on the [clientname] field that the current record is on.

** All the folders being created would be in a central server file that all computers have read/write access to, and is designated as the "L" drive in their networks.

** A consideration would be the folder name creation, since some of the [clientname] fields do include / may include invalid characters for folder names, so that in the example above, the "/"s would be changed to "-"s

I do understand access pretty well (but am always learning), and have limited knowledge on scripting, so any help would be greatly appreciated.

Thanx - JR
