site behaves differently when i check it on my browser

i test my site in preview mode, and when i check it on browser it behaves differently
i have a site, where my customer enters some data, which i collect in database, then with pressing a button the customer goes to the next page, where there is the appropriate product
i made my page, connected the text inputs to the database, and on the next page i added dynamic dataset, and connect text boxes to the database to retrieve the appropriate product and present it to the customer
on preview mode, it works right
on browser, nothing happens on the next page(where the product should be shown), data gets saved in the live database though.
anyone has any idea?

Have you checked the collection permissions?

well, that fixed the problem
sorry for the stupid question
and thank you very much that was helpful
