You'll need to give us some more to go on than that. Start by telling us which version of RoboHelp you are using. Then tell us exactly what you are struggling with.
I am using Robohelp 10. I created a document Folder in Sharepoint. When I attempt to generate and publish the webhelp does not generate in Sharepoint. Any assistance you can provide would be great.
Check out this Adobe blog post and see if it helps: http://blogs.adobe.com/techcomm/2012/10/integrating-robohelp-projects-with-sharepoint.html. It would also be a good idea to ensure you have the appropriate SharePoint permissions for RoboHelp to write to your document folder.
