Gantt chart mark - "requires end => start"

[Esther Tang]

I followed the instructions here to create a Gantt chart using the chart macro: https://community.atlassian.com/t5/Confluence-questions/how-to-display-project-tasks-in-gantt-chart/qaq-p/437786

However, I keep getting "requires end => start" when I click preview (screenshots below). Can anyone provide a solution to this? Thanks!

Hello Esther,

Welcome to Atlassian Community. It's nice to meet you!

In your first row, you have Start Date set to 06/25/2013, but the end date is set to 04/10/2013. This is the cause of the error, which is telling you that the end date has to be greater than or equal to the start date.

Please try changing your End Date to a 06/25/2013 or later, and see if you still have the error.

Regards,

Shannon
