> Hi there, I’m creating a carbon emissions calculator and I’m wondering if there is a possibility for the user of the app to: Add a project Which leads to calculator page and saves calculations in that project Then, a page called My Projects will hold all the projects added to the app After clicking on each project, it’ll open a project details page with a table of calculations that have been made I’ve already created the calculator, but I’m not sure how to add that project layer to the app, …

You will need to become familiar with some of the following:

• [Math column](https://www.glideapps.com/docs/reference/computed-columns/math-column): Allows you to make calculations based off basic number columns.  
• [User-specific columns](https://www.glideapps.com/docs/reference/security-and-user-data/user-specific-data): Your basic columns are either global (all user of the app see the same data) or user-specific (two users will see different values of the same cell). These are used in calculators if you want each user to have their own calculations within the same calculator.  
• [Choice component](https://www.glideapps.com/docs/reference/components/choice-component): Might be useful if you have multiple services to choose from in your calculator  
• [How to create a custom form](https://community.glideapps.com/t/how-do-i-create-a-custom-form/25014) by @Darren_Murphy. A calculator is a use case of a custom form.
