# Checklists (https://docs.carlio.app/docs/tasks/work-a-task-checklist) Answer each checklist line of a task and add a note The checklist lists the steps of a task. Each line receives one answer. **Requirements:** the **Edit Any Task** permission, or an assignment to the task. Other team members read the checklist but cannot answer it. ## Steps [#steps] 1. Open the task page. 2. Select the **Checklist** tab. The count on the tab shows the number of answered lines. 3. For each line, select one answer button. 4. Optional: enter text in the **Note for this line…** field of the line. The card header shows the progress, for example **4 of 13 checked**. When a line has the answer **Problem**, the header adds the count, for example **4 of 13 checked · 1 problem**. ## Answers [#answers] | Button | Meaning | | ----------- | ------------------------------------- | | **OK** | The line passed. | | **Problem** | The line failed. | | **N/A** | The line does not apply to this task. | A line that has no answer reads **Not checked** for team members who cannot answer it. ## Notes [#notes] A note saves when the cursor leaves the note field, if the line already has an answer. A note on a line without an answer is sent together with the next answer button that is selected. Selecting another answer button changes the answer of a line. The note stays. ## Notifications [#notifications] Each answer creates the notification **Checklist updated** for the team members assigned to the task and the team members who follow it. The default delivery is the in-app feed only. ## Limits [#limits] * A task has at most 100 checklist lines. * A line holds at most 200 characters. * A note holds at most 500 characters. * The message **This task has no checklist.** appears when the task has no lines. The lines of a task are set when the task is created and change in the **Edit Task** dialog. See [Create a task](/docs/tasks/create-a-task). The default lines of each task type are edited on the **Task Checklists** settings page.
