DHCP VLAN setup help

[bowlingcabbages]

Hi, i am new to packet tracer and I am having a problem with setting a V Lan with my DHCP server. It keeps saying DHCP failed and I have tried everything and still confused on what's wrong with it. I added my file, can someone help check what's wrong. Each AP is suppose to get a specific IP range

You are creating you DHCP scope wrongly. If you are using 192.168.99.0, the gateway must be on the same network. You can choose for example 192.168.99.1. But, you can not pickup an IP address from another network to be your gateway on this network.

Always put the gateway on the same IP range as the network.

You added vlan 10 with the same IP address on both multilayer switch. This will create conflict. If you used ip address 192.168.10.1 in one switch, use 192.168.10.2 in the other switch. 

interface Vlan10

mac-address 0001.c906.3c01

ip address 192.168.10.1 255.255.255.0

ip helper-address 192.168.99.3

Your DHCP server is connect in trunk mode. Server do not undestand trunk. 

You can check the Laptop and the PC in order to understand how things works with DHCP.
