# Fishbowl: "Product cannot be its own Kit child"

> You tried to add a product to its own Kit as a child component, which creates a circular reference.

## What it means
You attempted to add a product to its own Kit structure as a child component. A Kit (assembly) can only contain different products as child components—it cannot include itself, which would create a logical loop.

## What to check
- Verify the child product you're adding is different from the Kit's own product ID or name
- If copying product configurations, ensure you selected a different product for the child, not the parent
- Check whether you meant to add a different product or edit a different Kit instead
