VLAN activation DHCP router cisco

DA3M0N
Level 1
Level 1

Hello, I'm currently taking a computer science course and I need to use a cisco router to use the DHCP protocol to automatically assign ip addresses to two vlan on actives on a switch. The switch is well configured, the switch and router are connected in RJ45 on their trunk ports, I have declared vlan 10-20 in VLAN_A and VLAN_B on the switch, the problem is that I can not access the "conf-subif" commands such as "int gi 1.10" does not work. I do not understand where the error comes from, I follow the tutorial present on cisco.
I'm attaching a screenshot of my commands and the link to the tutorial I'm following.

Cisco interface use number x/x not x

That why when you enter e 1.10 is reject 

You need to see how router number it port

Do

Show interface and check
