Shell Script Calc & Forward Slash

[jnolla]

I'm trying to use Applescript to run a series of shell commands. I have encoutered a problem while creating the calculation, that will be sent as an Applescript.

do shell script" & Quote( " chmod 770 " & Substitute ( Preferences::Path ; " "; "" ) & "Contacts") &"

The problem comes with files and folders that contain spaces in their name " ". I'm using the Substitute Function, but the outcome is not what I'm expecting.

Applescript needs "" two forward slashes to refecence spaces " ". But no matter what I input on the data that will substitute spaces, I never get the "" needed by the Applescript.

"" returns ""

"" gives me an error

"" returns ""

I have also tried / /, but that doesn't seem to work.

Can some one point me in the right path?

Thanks
