Just to clarify, the constraints of single window have be replaced
by the constraints of double window, thanks again

Thanks for any help you might be able to provide.........
I have built a DC Component for window trim for a single window, all works fine.
I have built a DC Component for window trim for a Double window, all works fine.
Here is the issue, when placed by them selves they work fine, when place together
the second component will pull information from the first component, and then the
calculations turn red and the component is not regenerated correctly.

thanks for any help
