Thanks Jack, sounds like a good set up. I have been using the normal buy button, but running into some issues… hence the experimentation! > [@Using Math column for Price in Stripe buy button](https://community.glideapps.com/t/using-math-column-for-price-in-stripe-buy-button/8926/13): > > Hey @Mark > > Given limitations with row owners and computed columns, I’m using a formula in a separate google sheet to calculate the price.

However, even when it updates in gsheets and then the data editor (where the checks are made allowing them to proceed), there’s still a delay to the app and the user can click through to buy before the price is updated. > > I can’t think of any other ways to get the correct amount.
