Add some things to my code

max budget 60. For the construction of the website I use HTML, CSS, ejs, JavaScript, for the database MongoDB & mongoose, for the map leaflet map and generally for uploading local (localhost) nodejs, expressjs & gulp. Finally I have my files organized according to the MVC model. 1) database connection, save username (which if it can be opened in modal to put its name even better), locations on the map (so far I have not changed the map, I have just put a popup when you press with the coordinates of the point) and the answers to the questionnaire. 2) To be able to go to the next page only if the user has filled in all the questions and has placed locations on the map. 3) the marker of the map that the user will put on the site to be editable, ie simply to write text in the user or otherwise to have some options from which he can choose one. (maybe better the second).
