adding Script reference in another unit

Hi Team,

                I have one project in that fifteen applications are there. Now i want to different 15 application with different projects. I have created one projects framework and i have created one more project i have given the reference framework to the project. But my application is not working. I am getting the error " other project unit references not part of the project" getting error message.

Framework is given reference to the particular project if any line update in to the framework it will reflect to all projects. 

Could you please help me how to resolve the issues? how to add the references to another project? i gone through smartbear community it is not working
