Gantt is undefined

I have a Pro license Commercial edition. According to the documentation here (Multiple Charts on a Page Gantt Docs), I should be able to call Gantt.getGanttInstance() and be able to create an additional instance on a page. However, whenever I call “Gantt” (with a captial “G”), it returns undefined.

I have version dhtmlxGantt v.7.1.7 Professional. My license is Commercial. Is there something I am doing wrong?

Thanks,

Jeff
