# Some rollup properties do not show up in the app builder

There might be instances where some Rollup properties, do not appear in the app builder by default. Rollup properties depend on data from other linked databases to calculate their values accurately. When a Rollup property is added to a database in Notion, NotionApps does not automatically have access to the data in the linked database. Consequently, the Rollup property does not show up in the app builder until access is granted.

{% hint style="info" %}
TL: DR; Provide NotionApps access to the database linked to the rollup property and click on "Reload". Then open **Databases → Calculated properties** to see the recipe and Recalculate toggle.
{% endhint %}

To show the missing Rollup properties in NotionApps, you must follow a few simple steps to authorize access to the linked database:

1. Access the "Databases" Tab: In the NotionApps app builder, navigate to the "Databases" tab through the sidebar. Here, you will find the list of databases you have already linked to NotionApps.
2. Authorize Access: Once on the "Databases" tab, you need to click on the "Manage Databases" button. Upon clicking, a Notion page authorization site will open.
3. Confirm Access: On the authorization page, you must confirm access permissions for NotionApps to read data from the linked database. This is a one-time process, and it allows NotionApps to collect the data required for the missing Rollup properties.
4. Reload App Builder: After successfully confirming access, you need to click on the "Reload" button within the NotionApps app builder.

This action refreshes the database information in our system, and now the missing Rollup properties associated with the authorized linked database will be available for use in the app builder.

After Reload, open **Calculated properties** if you want NotionApps to recalculate sum / count / average / min / max from the recipe. Guide: [Recalculate calculated properties](https://docs.notionapps.com/how-to-guides/recalculate-calculated-properties).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.notionapps.com/troubleshooting/some-rollup-properties-do-not-show-up-in-the-app-builder.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
