Display text from elsewhere on page

[Phil Laks]

Is there some functionality within Confluence to represent a string or variable from elsewhere on the page to auto-update when changed.  For example:
The top of the page says "400" and you want to say whatever is at the top of the page multiple times later in your document.  Can you simply add a macro to reference the initial value, so that when that value is changed or updated the rest of the page shows those updates at each reference?

Yup! In short:

• Use an "Excerpt macro" with an embedded table of data on the pages with the info of interest. Note that the "Excerpt macro" doesn't show on the page, but the table does.
• Put an "Excerpt include macro" on the page where you want to aggregate the data from the other pages.
