I am trying to create an object ONCE to write a logfile and want various Functions to be able to use the same object, How can I do this?

Right now I am using the following within an click event and it works fine, but I want to be able to just use my Logfile.Writeline command within any function to append to the same file...

Set Logfile = fso.CreateTextFile("c:\installlog.txt", True)
Logfile.WriteLine " Install Log Created" & " " & (Now)


Thanks.
