Hi. Hoping someone can help me. I am trying to do something that I believe should be simple to do with appsheet but have not been able to figure out. I would like to create an app where: (1) the user enters their income (and the the app references a lookup table in Google sheets to (2) determine their federal tax rate and (3) calculate the taxes they pay for various federal services (the lookup table is a column that lists government services and a second column that shows the % of taxes each service is. After the user enters their income I would like the app to show a doughnut chart showing how much they spend on their taxes for each government service. Finally I do not want to store any user data - I want the app to only store the income long enough to generate the chart. As such no records will be kept. I have not been able to figure out how to do this - in particular nor storing the income data. Is this idea even possible with appsheet? If so how should the data / tables / Google sheets be architected? Many many thanks in advance. Kevin
