Hey @STyson if you see the HubSpot logo on the top right of you page it means you have access to that page.
From what I can tell it looks like you domain sillygoosestudios.ca is not connected to HubSpot:
You need to ensure you have followed all the steps to connect your domain to HubSpot. It looks like you already have a site setup on this domain on shopify, so you will need to create another subdomain in your domain provider and connect this to HubSpot (such as signup.sillygoosestudios.ca) as a single domain can’t point to 2 places.
Once that’s done, you can choose the url of your content within the content editor.
What’s happening right now, is you told the HubSpot page to be on the domain sillygoosestudios.ca, but that domain is not connected to HubSpot, so it has no access to publish a page on that domain.
