I can't sign up for an activity
Don't see a signup button, or can't sign up? Walk through these points.
Signup window closed
The organization has set a period in which you can sign up. If that message is there, you also see between which moments it is possible.
The activity is full
All spots are taken. You can join the waiting list. When a spot opens up, all waiting-list participants get an e-mail; whoever responds first gets the spot.
You are not a member yet
If it says Members only, you first have to register with the organization. See Become a member of an organization.
You are missing a membership or tokens
The ticket belongs to a membership you do not have, or costs more tokens than your balance. Buy a tokencard or take out the matching membership. See Memberships and tokencards.
You are already signed up for something that conflicts
Some organizations do not let you combine certain activities. You then get a message with the activities you are already signed up for. Cancel those first if you want to switch.
Guest signup does not work here
Whether you can join without an account is up to the organization. Some only allow signing up with an account.
If it is a ticket paid with tokens or with a membership, you need an account anyway: those belong to your membership of the organization. A ticket that simply costs money you can usually check out as a guest, except at organizations that only accept participants with an account. See Create an account.
You get an e-mail instead of the payment page
If you check out as a guest with an e-mail address that is already known to DoToo, we first send a link to that address. Open the link to continue to the payment page. See Pay.
Your confirmation e-mail has expired
If you signed up as a guest, you have to click the link in the confirmation e-mail within 24 hours. If that did not work, sign up again. The same goes for the link to complete your order: if it has expired, check out again.
Still not working?
Contact the organization itself; they can see your situation and can still add you. If you suspect an outage in DoToo, use Support.
