Can't move a domain to my website

I want to move my square space domain to my square space webpage.  

I tried settings -> domains -> use a domain I own

I get 2 warnings:

    This domain is registered on another Squarespace site

     This domain is already associated with a Squarespace site

I can't figure out how to get around this.

Any thoughts?

Here is the Squarespace Help guide that addresses this:

Hi @ccwillmore, wondering if you had any luck here. I am having the same issue - a squarespace domain that I purchased, unconnected to any site. I now want to connect it to a trial site I created and I'm getting the same error as you mentioned.

I recommend you get in touch with Squarespace Customer Care and ask them to help you to troubleshoot this. At this time of day you should be able to contact them for an interactive online chat.

Thanks @paul2009 , I was able to get through last night on chat and they were really helpful. It feels really obvious now but in case it helps anyone else - I hadn't set up a subscription on the destination website yet. So once that's done it should work fine. 🙈
