Excel Gantt Chart question

[Darl Nagelkirk]

In my current excel Gantt chart I have the year in weeks across the top axis. I have two bars on the chart the first bar represents a duration of time for a task, if the task goes past week 52 is starts again at the beginning of the chart to represent week one of the first week of the year. My issue is I cannot get the second bar or task to do the same thing.

Any solutions?
