I'm having trouble with the vote/port system.

Hello there. Were sorry to hear you're having trouble. Could you describe the problems you are experiencing?

I keep getting the error:

You cannot trigger this objective yet

What trigger are you trying to use?

The "click to go to spawn" in the "clickie" book I got when I joined the server.

bump

I'm not sure about the book as I lost mine long ago.
In the mean time the command for teleporting to spawn is:

/trigger Port set 1

Try that and see how you go.

That gives the same error.

I would say your only other option would be to @admin in Discord and organise a time when you're both online.
Sorry I can't help further.
