Hello everyone, I’m brand new to Glide and have just started with the free plan. I’m working on an app with tables for our tennis club members, a drinks menu, and an area where I can add drinks for a specific member. At the end of the evening, I want to calculate a total amount for the member (for that evening), collect the money from them, and set the balance to zero. I’ve already made several steps of progress, but now I’m stuck at the point where I want to set the guest’s total to zero. Can anyone help me? Thank you in advance for your help. Best regards, Richard ---

You might want to use a scheduled workflow to automatically calculate and set balance to zero. This is only available on paid plan tho. Sorry about that. ---

I’m pretty far with the development of the app. I just have to set up a button for checkout. Can someone tell me how to configure the action? I wanted to use the set column value. But the app just offers me fixed columns, not the computed or look up columns. How can I fix this? ---

Computed columns are read only. You need basic columns to write. ---

Do you have the members log into the app? I feel like this is just a problem of structuring the data into a Line Items table, and submit them into an Order when they’re completed. ---

No, I have no users in this case. Is this available in the free plan? I suppose not, right? How do i activate this in my free plan, in case this is included? Thanks Richard ---

It should if you structure the data somewhat like this. However, in your case there are no users, there should be a unique ID set somewhere in the flow to know which items belong to which orders. > [@Adding Multiple Products to an order](https://community.glideapps.com/t/adding-multiple-products-to-an-order/73378/5): > > The flow would look like this, assuming your users are signed in: Add a Cart table that would contain the order id, the item id and the quantity. In your users table, add a “current order ID” column. Assuming you have an Items screen, on the entry to the details view of that screen, check if your “current order ID” is empty. If empty, set a unique ID to the “current order ID” column, then show them the details screen. Else just show them the details screen without doing anything. Add a form in…
