I have 5 spreadsheets that are shared with other staff in the office. We share these spreadsheets using Google drive. Each staff has the ability to edit the spreadsheets. The spreadsheets are "shown" on a wall using an overhead projector. What I am trying to figure out is if there is a way to automatically alternate (or rotate) each spreadsheet. For example, spreadsheet 1 would "show" on the wall for approx. 30 seconds, then spreadsheet 2 would "show" on the wall for approx. 30 seconds, etc. I am new to all of this. Let me say in advance ...your patience is appreciated!
