Hi Charles, thank you for your help.

I am going to try to explain a bit better what I want to achieve.

Let´s say that I have a master file where I want to list all my company´s customers and details on such customers (foundation year, number of employees, sales revenue...) So we have the "master file" and a separate file for each customer, let´s say "A", "B", "C".

Imagine that I have the following sections (bookmarks) for each customer "general information", "contact details" and "products we sell to the customer". Then, each section must be also in the master file. I could use the InsertText field or I could copy and paste as a link so each time I modify each customer´s file I get the same amended items on the master file. However, imagine that I add new products to the "products we sell to the customer" for each customer. Those new lines, will not appear on the master file. Perhaps, the only solution is to write a macro?

Thanks
