Hello

I need to know how I can permit members to add only 1 item in a collection, which they can change or delete, but can not add 2 items.

When a member adds an item into the collection, the member ID is stored in the \_owner field.

When a customer clicks submit button, you can check if the entry with such [member ID](https://www.wix.com/velo/reference/wix-members/currentmember/getmember) exists in the collection (e.g. [query](https://www.wix.com/velo/reference/wix-data/query) it) and based on the result either submit the item or display an error for example.
