Hi,

Thanks for your response. I honestly do not know how the
sheets are linked. Could you please tell me how to find
out this?

I have not worked with excel extensively, but I am a quick
learner.

Also, of all thew linking styles, which one do you advise
that I use for new projects that are similar to this?

They are asking me to design a new one based on my
understanding of the existing one...so any help would be
highly appreciated.

Thanks!

Ken
