Groups permissions

[wooolF[RM]]

Mmkay, for 3rd day I'm trying to figure out how to get this to work:

I have 3 groups:
SiTEOP : can upload anywhere
TRADER : can upload anywhere but can't delete folders/files from any folder except under /UPLOAD (ONLY their own folders/files)
LEECH : can't upload anywhere except under /UPLOAD and can't delete folder/files from any folder except under /UPLOAD (ONLY their own folders/files)

I have chmodded all folders on FTP to 777
User flags:
SiTEOP :1THL
TRADER : 3U
LEECH : 3F

in my ioFTPD.ini I have this :

Upload = /UPLOAD/* * Everybody can upload here
Upload = * !=LEECH * Leecher can't upload anywhere, but above
Resume = * *
Download = * *
MakeDir = /UPLOAD/* Everybody can create dirs here
MakeDir = * !=LEECH * Leecher can't make a dir anywhere but in upload
RemoveOwnDir = * *
RemoveDir = * 1VM
Rename = * 1VM
RenameOwn = * *
Overwrite = * 1VM
Delete = * 1VM
DeleteOwn = * *
..skipped..

Right now it works so anyone (except SiTEOPs) can upload only under /UPLOAD... SiTEOPs are ok, their permissions are good enough...
I have tried to figure those perms for 3 days now and finally gave up
I would be very apreciatted if anyone could help me, thanx
