AppleScript path to application support

Hi, this script works but the folder I want to move "Omnis" ends up in the global "application support" folder.

I'm trying to get it moved to the users "application support" folder.

I can't figure out how to define, and set, the path to [current user]/Library/application support

-----

set dT to (path to desktop) -- this returns the current user's desktop path

set a to (path to application support) -- this returns the current user's "application support" folder

tell application "Finder"

set sourceFolder to folder "Omnis" of dT

set destFolder to folder a

move sourceFolder to destFolder with replacing

end tell
