Launchd agents not working

Question

Hi,
I have created a user launchd agent saved in ~/Library/LaunchAgents and is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.Keith.ThingsBackupLaunchd</string>
<key>ProgramArguments</key>
<array>
<string>/Library/Scripts/Folder Action Scripts/Copy Things to Dropbox.scpt</string>
</array>
<key>StartInterval</key>
<integer>30</integer>
</dict>
</plist>
Basically it calls a script every 30 secs (only for testing, it will actually only call the script when a file gets modified) which is as follows:
tell application "Finder"
set sfolder to folder "Things" of folder "Cultured Code" of folder "Application Support" of folder "Library" of folder "Keith" of folder "Users" of startup disk
set tfolder to folder "Dropbox" of folder "Keith" of folder "Users" of startup disk
duplicate sfolder to tfolder with replacing
end tell
Copying my Things DB folder to my Dropbox folder. The Script works fine but the Launchd Agent does not.
In console I am getting the following error message:
22/07/2010 22:41:18 com.apple.launchd.peruser.501184 (com.Keith.ThingsBackupLaunchd392) posix_spawn("/Library/Scripts/Folder Action Scripts/Copy Things to Dropbox.scpt", ...): Permission denied
22/07/2010 22:41:18 com.apple.launchd.peruser.501184 (com.Keith.ThingsBackupLaunchd392) Exited with exit code: 1
Actually it doesn't seem to matter what I try to call, even trying to start an app at a specific time with a launchd agent produces the same error.
Any ideas?
Thanks

Thanks for the suggestions,
I have tried lots of variations but still no closer. Currently I have:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.MyLaunchd</string>
<key>ProgramArguments</key>
<array>
<string>/bin/bash</string>
<string>cp</string>
<string>-R</string>
<string>-f</string>
<string>/Users/Keith/Library/Application\ Support/Prog /Users/Keith/Dropbox/Backups/</string>
</array>
<key>WatchPaths</key>
<array>
<string>/Users/Keith/Library/Application Support/Prog</string>
</array>
</dict>
</plist>
This errors in the console with
17/08/2010 21:54:39 com.MyLaunchd[4224] usage: cp [-R [-H | -L | -P]] [-fi | -n] [-apvX] source_file target_file
17/08/2010 21:54:39 com.MyLaunchd[4224] cp [-R [-H | -L | -P]] [-fi | -n] [-apvX] source_file ... target_directory
17/08/2010 21:54:39 com.apple.launchd.peruser.501[268] (com.MyLaunchd[4224]) Exited with exit code: 64
So I definitely know it is call the launchd when the folder is modified.
Any further suggestions?
