Unable to publish course

Unable to publish course

Hi, 

I have created a course on Zoho People LMS. Uploaded the files, enabled the settings but for some reason when I click on publish an errors pops up 'Add at least one file or link to publish this course.

Also, I am unable to add members the 'click here to add new members' does not have a hyperlink to enable me to select members. 

Am I missing something?
