Data from multiple pages to be displayed in a single line on the dataset.

Hello,
I’m a complete noob in web dev & wix. I have created a site which takes input from users & populates in the content manager fields. My site has 1-2 text boxes with a button(linked to dataset, action -submit & move to new page).
The problem is every time I move to the next page, I end up creating a new line in the dataset, I require text boxes from multiple pages to be a single entry in the data set and line should be changed only after the last text box is submitted. There is a next page option in the “connect to data” settings but it is greyed out.

I’m not using the dev mode or any code(GUI only). Can someone please help? If this is not the correct place to post the same, please advise.
