Hi, If the items that you want to enumerate are entities, like for example a table of trees, you can simply enable the option "Show row number in tables" in the entity editor in Collect Survey Designer: the number of each row will be automatically shown in the data entry form. If you need to do something more complex and you want to use that number in other expressions, you can define a calculated attribute like "tree_num" for example and you can define this expression as Default Value expression: "idm:position()". The result will be very similar to the previous solution. You can try to enable this option both the solutions and see how the data entry form appears using in the "Preview". Thanks
