You may need to make changes to your project along the way! 

To Edit your project from your dashboard, you can either select the project name or the edit button as seen here: 

This will take you back into your project builder and you can make any needed adjustments. You can edit your project at any time. From there you can set the project back to active or pause it.

Note: While you are editing your project in the project builder, the project will be in a paused state and not collecting responses. The "Save & close" will leave this project in a paused state, whereas the "Reactivate" will put this back in field as an active project.
