I am wondering if I am going to have a deployment problem with the code I setup.

I have a C#. web form asp.net 2010 application that I added some web pages to. The user selects my new web pages off of the same main from the web site.

There is some data access code that I decided to use that is in a separate 'project folder'  than the 'project folder' that I am using. Since the code  I am using is in separate project folders, I am thinking the this may affect the way I setup my code. Maybe I need to not reuse the code in the other 'proejct' folder and put the code into my 'proejct folder'.

I know the code has 3 different deployment setup? Can  you tell me what I need to look at to determine if I have a deployment problem?
