Thanks for replying so soon Paul.
I am incorrectly using the term "Master Document". I am using one document and subsequently linking about 30 pieces of text to another set of documents (>10) which are currently templates (.dotx) This currently works very well, However I am looking to make the "Saving" function a little more automated and elegant, leaving only the selection of the folder location as the user interaction.

Of the 4 pieces of text in each template that I want to use 3 of them are linked from the first doc; being docnumber (4digits), sitename (2-3 words), personname (2 words) these are the bookmarks that you are refering to; so to answer your questionas best I can: I believe the text is contained within the bookmarks. The doctype is a string of normal text in the document.

We currently have a naming convention being "docnumber doctype sitename personname.pdf". This is a entered manually for each document on "save". My thinking is; as the information is already in the document content and Word uses the Title property as the suggested file name on save, I might be able to assemble the four pieces of text, concatenate them and make that string the Title property. There would be no issue with concatenting the strings as a line in the document prior to the macro making the new Title property if it simplfies the macro.

Regards.
