Can you master fix a graph table format to ensure consistency, and only allow people to input the data table that automatically produces the graphs / charts ?

I need to have staff in various countries compile performance data on bar graphs and pie charts, but need to fix the style and formatting, so only the data can be amdended on a monthly basis. I need to stop too much variation in formats being introduced

Hi Paul, Thank you for your post, in answer to your question, you can set security on your presentation which will only two options, you can set a password to allow only certain users with that password to open it, and/or you can set a password that only allows those users who have the password to modify the presentation.
Follow these steps; in your presentation; select the menu option; Tools>Options and click the Security Tab, on this tab you have the two options mentioned above, apply the settings you require, and click OK. I hope that has helped, if so please click the Resolved link, best regards Pete.
