# Checks and flags

> See the project's validation findings on the log, fix or mark them checked, and flag rows.

## Checks

The Logs & Sheets page shows the project's [validation](/manage/table-editor/validation) findings
where they are on the log, along with the log's own depth check (gaps between strata,
and strata that overlap).

- With one location open, it is checked against the data as you work. Other locations
  show the project's last validation run.
- Errors show as red pins. Warnings and advice show too with **Show > Check warnings and
  advice**.
- Next to the comment count, a chip gives the location's errors and warnings: click it
  to list only the findings. The refresh button checks the location again.

### Deal with a finding

Open a finding to see what's wrong.

- **Fix it**: its fix buttons (or **Open the row to fix**) open the
  [edit card](/manage/logs-and-sheets/editing-on-the-log) with the new value typed in. It clears on
  the next check.
- **Mark checked**, when it's right as it is. **Reopen** takes that back.
- **All N like this, on every location** lists every finding of that rule. From there,
  **Check every location** brings them all up to date, and **Mark all checked** clears
  them with one reason, which goes in the comment register.

Findings are advice, there to support what engineers say on the log: they never stop a
log being checked or approved (see
[Checking and approving](/manage/logs-and-sheets/checking-and-approving)).

## Flags

Click a data row and choose **Flag** on the edit card. Write what's wrong, pick a
priority, and press **Flag**.

It is the row's own flag: the same one the table editor and the [Flags](/manage/flags)
screen show. On the log it is an orange flag pin, with a red dot for High and Highest.
Resolve it with the tick, or **Reopen** or **Unflag** it from its **...** menu; the
change shows everywhere.

Use **Filter > Has flags** on the locations list to find locations with open flags.
