# Make a task wait for another

> Mark which tasks block a task, spot date conflicts and see blocked work on the board and the dashboard.

Some work can only start when other work is finished: the campaigns can only go live once the ads are set up. Mark those other tasks as blocking it, and everyone sees what the task is waiting for.

## Mark what blocks a task

1. Open the task that has to wait. Under **Blocked By** in the panel on the right, choose **Add blocking task**.
2. Search for the tasks that have to be finished first. The search covers every project, so a task can wait for work in another project.
3. Click each task that blocks this one, then choose **Save**.

The tasks you chose are listed under **Blocked By**, with their project and status. Click one to open it. That task lists the waiting task under **Blocking**.

When a blocking task is completed, it leaves the list. When the last one is done, the person assigned to the waiting task gets a notification that the work can start.

## Spot date conflicts

When a blocking task is due after the task that waits for it, the plan cannot work. The blocking task then shows **Due date conflict: blocker due later** in red. Move one of the two due dates to solve it.

To change the list later, choose **Edit blockers**.

## See blocked work

On the board, a blocked task has a red no-entry sign in front of its title. On the dashboard, the **Blocked Items** widget lists every blocked task with the tasks it waits for.
