# Ask Rex questions

> Write questions that get useful answers, and read Rex's sources and gaps before you rely on them.

## Asking well

Rex answers best when a question is narrow. Name the date range, the Location, the customer or job, and what you want back. Compare:

* Broad: "How are we doing?"
* Specific: "Which completed jobs at this Location from last quarter have no invoice?"

To point Rex at specific data, type **@** in the composer on supported pages and select a record, view, or connector. Upload files separately. See [Get started with Rex](/rex/get-started).

## Questions worth asking

* Which completed jobs have no invoice?
* Which proposals sent this month haven't been signed?
* What does the CRM show for this customer compared with the project here?
* Which open tasks on this project are past due?

Answers depend on the data your account holds and the tools Rex can read in your Location, so results vary between accounts.

## Reading an answer

Review the source links Rex provides. If an answer doesn't include them, ask Rex which sources it used. Before acting:

1. **Open the linked sources.** Confirm the records match what you asked about.
2. **Read any missing-data notes.** Rex may note tools it couldn't reach or records it couldn't find, but don't assume every gap is flagged.
3. **Don't read a gap as zero.** If a connector didn't return data, the true number is unknown. An empty result can mean the data wasn't available.
4. **Don't assume freshness.** A connector that shows as connected may still be missing recent changes or older records.

When something looks off, ask a follow-up that names the source, such as asking Rex to list the invoices it checked for a job.

## When answers come back thin

* Check the selected Location and which Locations are included in the answer. Scope depends on your role and account.
* Ask an Administrator whether Rex has read access to that tool in **Settings → Connections**. See [Rex permissions](/rex/permissions).
* Check the connector itself in the [connectors overview](/connectors/overview); connections can expire.
* Start a **New conversation** if earlier context is steering answers.

## From answers to actions

Asking doesn't change anything. When you want Rex to update a record or draft an email, see [Act with Rex](/rex/act).
