# Re-eliciting slots
<a name="reelicit-slots"></a>

 You can configure your bot to re-elicit a slot that has already been filled by setting that slot value to **null** and setting the next step in the conversation to loop back to eliciting that slot. For example, you may want to re-elicit a slot after your customer declines a confirmation of the slot elicitation based on extra information, as in the following conversation: 

![\[A conversation eliciting a customer's meat preference for a food order.\]](http://docs.aws.amazon.com/lexv2/latest/dg/images/slots/order-food.png)


You can configure a loop from the confirmation response back to re-elicit the slot with either the intent editor or the [Using Visual conversation builder](visual-conversation-builder.md).

**Note**  
You can loop back to re-elicit a slot at any point in the conversation provided that you set that slot value to **null** beforehand.

**Reproducing the above example with the intent editor**

1. In the **Confirmation** section of the intent editor, select the right arrow next to **Prompts to confirm the intent** to expand the section.

1. Select **Advanced options** at the bottom.

1. In the **Decline response** section, select the right arrow next to **Set values** to expand the section. Fill in this section with the following steps, as in the image below:

   1. Set the slot value you want to re-elicit to **null**. In this example, we want to re-elicit the `Meat` slot, so we input **\$1Meat\$1 = null** in the **Slot values** section.

   1. In the dropdown menu under **Next step in conversation**, choose **Elicit a slot**.

   1. A **Slot** section will appear. In the dropdown menu under it, choose the slot you want to re-elicit.

   1. Select **Update options** to confirm your changes.
