I’d like to have more UX options. It’s really hard for me not to be able to use variables, not even the data in the inputs. I want to use Baserow—I love that it’s open source, but I feel like my hands are tied.
Hey @josefernandez, Thank you for your feedback. To ensure I understand correctly, could you clarify what you mean here 
Hi, thanks for your reply. Let me explain. I feel quite limited when trying to build a better user experience using only the data from the tables or the user. For example, I want to display aggregated values in an input field, but it only returns the ID.
I thought I could create a data source using those ID values, but that doesn’t seem possible either. Ideally, I would like to be able to create variables to manipulate data and perform operations within the app.
Do you know if there’s any way to achieve this or any workaround?
Thanks in advance!
Thanks @josefernandez! I’ve shared your feedback with the Application Builder team for review. 
Hey @josefernandez thanks for the feedback.
Advanced formulas are coming. You will be able to apply formulas on the values in the builder, I think it should cover at least partially what you need. Variables are also on the roadmap.
You have a summary data source to get aggregated values from a table, does it help?
I’m not sure I understand what you want to do but you can generate a link to a page (potentially the same page) and fill a query parameter in with the data from the input. When you click on the link it changes the URL and the parameter can be used to filter a data source. Would it be a temporary solution?
