Wu-ftpd and uid / gid allow

Dear all
	I am having a difficulty in configuring wu to use the
deny-uid/gid and allow-uid/gid. I wish to block all uid/gid except a
range of numbers, I have tried the following 

deny-uid %-65595
deny-gid %-65595

allow-uid %1234-4321
allow-gid %1234-4321

This block access from all with message "FTP LOGIN REFUSED (username in
denied-uid) "

Can someone please enlighten me as to the correct method of entry 


	TIA Simon
