choose folder

Hi all..

When displaying the number of files in a folder from a dialog do u need to set a variable ?

I tried the following :-

count file in the folder (choose folder)
    display dialog "Today is: " & (current date) & ".  " & "You have : " & {count file} & " files within this folder." with title "Useful Information"

but the results always comes back as 4. regardless.

Seems it doesn't work.

example?
