configuring layer 3 switches as trunk mode

Hi,

I designed my network in Packet tracer as seen below.  am trying to configure the switched as trunk but am keep getting this message (under the picture)

Command rejected: An interface whose trunk encapsulation is "Auto" can not be configured to "trunk" mode.

Can anyone please help me what am doing wrong?

You need the command

You need the command switchport trunk encapsulation dot1q before you issue the switchport mode trunk command.
