Says my Commerce Page Isn't Found

Hi! I just created my website, and I have a Commerce feature where I sell my products. Whenever I try to access this feature, be it while logged into my Squarespace account or even on the website on someone else's computer, it says the page isn't found. This is driving me up the wall, as I input all the necessary information and obsessively double checked that I had created the page. Does anyone have any idea what could be wrong? Thank you!

Did you enable the page?
