cisco DHCP

Hi, I have setup a router, it's f0/1 was connect to a AP, IP: 172.16.100.1. My DHCP server was Windows server, IP: 172.16.0.100. I have created a DHCP scope(172.16.100.100-172.16.100.200) in it. but my cellphone cannot get IP from DHCP server.

I setup below command in my router;
int f0/1
ip helper-address 172.16.1.201.
Is there anything wrong?

what is 172.16.1.201? Try changing the helper-address command to the DHCP server and test.

int f0/1
ip helper-address 172.16.0.100
