❔ I have a project that I need to submit in 6 hours, but I'm stuck at one point.

Project: The project aims to develop a web interface where a minimum of 3 and a maximum of 5 people's names, surnames, and birthdates can be entered. The tasks to be done within this scope are as follows: A web interface should be developed for entering the information of the individuals. The controller related to the information input should be as follows: Name and surname fields cannot be left blank. The birthdate cannot be a date later than the current date. The birthdate cannot be a very old date. The data entered should be processed on the server-side using Razor Pages server-side .NET web technology. The calculation of age is expected to be performed on the server-side. After entering the information of 3 people from the web interface, they should be sorted from youngest to oldest and from oldest to youngest. The symbol "=" can be used between individuals of the same age in the display. An example display for 3 individuals is shown below: The entered person information from the web interface is expected to be stored in appropriate data structures in memory on the server-side. There is no expectation of saving and retrieving data from a database. The problem I'm facing: I'm adding the form data to object (People.Add(person);). However, since the form has a submit button, the page is being refreshed and everything I added is getting deleted.
