I want to be able to click on a button and it to do the following:

1. check to see if a path exists called c:\ and the contents of cell
A1 ie c:\bristol, if not then create one.

2. save the spreadsheet with the name cell a1 + cell a2 + the month and
year of cell a3.xls ie Bristol r-11111 april 2006.xls and put it into
the above directory.
