Shell script help

Why isn’t this script working?

cp -f /Users/steve/Desktop/picsFromServer/ /Users/steve/Photo Archive Manager/tempFolder/

in my app it is coded as this:

do shell script "cp -f " & POSIX path of thisPath & " " & POSIX path of tempFolder

I keep getting this error message:

Finder got an error: usage: cp [-R [-H | -L | -P]] [-f | -i | -n] [-pv] src target
cp [-R [-H | -L | -P]] [-f | -i | -n] [-pv] src1 … srcN directory (64)

I wasn’t escaping the spaces in my AS coded path. Doh. :lol:
