Display data through out site

I want a dashboard that I can update all the inputs (or updatable information) in one place but Ive been having problems trying to display data on the index page but it seems the data isn’t being registered as the updated rate (number).

How do I set up my data so I can update rates (numbers) in one place and display it through out the site?

You should be able to store that number in the database and refer to it dynamically. How are you saving and recalling the value now?
