I checked your account and understand what you are trying to achieve.
You want to have a multi-stage form submission, starting from first at ArchBestProject.com/1 to ArchBestProject.com/2 , ArchBestProject.com/3 , etc. with each next submission going into the same entry, but different field (title, name…).
Right now, each of your next form creates a NEW entry, rather than editing the previous one, that’s why the entries are added to different ‘lanes’, as can be seen below.

To achieve what you require, the _id of the first insertion should be passed to next stages (ex. via query parameters). Then it can be used to update the object. It requires coding/testing to see if an entry exists, and then edit it rather than create a new entry.
You can pass the above rough guidelines to the developers and experts at Wix Forum , where they will be able to help you with the coding. Wix Support does not provide detailed assistance with custom code.
Hello and welcome to the Wix Code community.
Check out the following article for a simple solution to a multistage form.
For a more customizable solution, you will have to write some code.
One approach is to pass the form responses as query parameters.
To send the parameters use wixLocation.to
To read the parameters, use wixLocation.query
A different approach to this is to save the form responses in the browser storage, then get them in the final stage, right before you save them to the collection.
Check out wix storage here
To save an item to the collection once its ready, use wixData.insert
Each approach has its own pros and cons.
If you have any specific questions feel free to post them here.
Good luck!
