I have a list of documents in an Excel Spreadsheet (a matrix per se), listing all documents with their #'s, document titles, what departments each belong to, & revision date. On a 2nd Tab, I'd like to return (link if anything changes on main tab) all documents that belong to a specific department. The way I set up the spreadsheet is with column headings for doc #, title, rev date, then the subsequent columns are each department. The rows are the various documents & I placed an "X" in the column of the department it pertains to. What formula can I use on the 2nd tab to return the list of a specific department?
