I have no problems with CCS or coding profiles. How ever I don't know how to code a v2 profile. I know the terms, but I wanted to open up a shop, to sell what I made. How do code a v2 profile to where it will work no matter on any account. I know when I would code something it would be out of place at times. It would be ok on one account or screen, but as soon as the coding goes to another acc. then it becomes problems and things don't line up right.
