What do you mean, how do you implement a circular reference in VBA? Why would you want to?

I'm creating a calculation based on a spreadsheet which contains circular refernce.

I don't think that explains anything to me. You have a circular reference, and now you want to create another? I still fail to see why you want to create something that most people would see as a problem.
