How to create multiple AC points

I have created a heat exchanger assembly that has 4 by 4"outlets. Each outlet is threaded and has been created in a seperatepart file. I have added 2 C points and 1 R point to the threadedoutlet part file. The assembly is good.

When I go to add an AC Point, I select the first outlet thread (the CPoint1) and select OK. All of the other CPoint1's from theother 3 threaded connection dissappear. Only the CPoint2's areleft. When I select one of them, then they all dissappear.

How can I create 4 ACpoints in my assembly? I have purchased theforefront studios book and it is a great help, but their exampleonly shows a valve assembly with 2 CPoints, hence it works forthem.

Any help would be great.

Thanks
