@davidm1708369 You can create a content block in ACS as well. To add the
logic, you can refer to the "Order Confirmation - Products Collection"
oob content block with syntax "context.rtEvent.ctx.products.length". It
refers to the " rtEvent_EVTwe_SHOP_OrderConfirmation" schema
(Administration > Development > Diagnosis > Data schemas). Similarly
based on your custom resource schema, you can add logic in a custom
content block.
