Circular parametric table family with formula

[BBV90]

Hello, 

I have made this family attached, which is circular table with parameters. I have the arrows in the Revit model space but it wont let me extend. It disappears once you pull the arrows. What part of the formulas or parameters Ill have to correct to have the size of the table adjustable and have more chairs around?

Why are you starting a new thread that is asking exactly what you asked yesterday in another thread?

You have way too many unnecessary parameters and ref planes. 

Same with a linear array, you need a length (perimeter of the circle) and the space between chairs in the array. I also modified the chair family so that its origin is at the center of the table, when the table diameter changes, the chair moved by associating a length parameter.

See the revised family.
