I'm working with three diferent files for quoting, the summary page, the
quote calculator, and the master data sheet.

The summary file (1 file) is 200 lines long with linked information from
each of the 200 quotes (200 files), that are all linked to the master data
file (1 file).

What I need is that when the master data file is updated, all 200 quote
files are updated without going in each quote files and update manually.

Summary file <-- 220 quote files <--- master data file.

Thanks for the help
