If a link refers to a hidden workpaper, it is not displayed on the screen.
Links are generated in a single calculation, not between different calculations.
Links work in single workpapers and across different workpapers in the same calculation.
Linked cells can't contain text or dates.
Links are automatically generated when there is a direct correlation of data.
Manually entering a formula automatically generates a link between cells.
Editing formulas automatically deletes a link unless the editing only reverses signage of the source value.
