Question: one page dynamically changing others

Hey all,

I'm looking for help with figuring out whether something is possible -- and if it is, if anyone has any suggestions on how to go about it.

Essentially I'm looking to create a stat sheet that affects other separate ones. So in effect, there would be a master stat sheet where you'd input stats and when inputted, it would dynamically affect other separate sheets.

I know this is possible in Excel and what not, but I'm looking for a way to transfer that online. My hope would be to modify one file that could then change a bunch of others simultaneously.

If anyone has any ideas, I'd really appreciate it. Thanks.
