Macro: Announcing Results and calling to other Macros?

Hiya, hoping people can help me with setting up a complicated macro. Using a game system that's not already supported so far as I'm aware, so needing to find the custom codes needed. Announcing result. How do I set a Macro up so that it compares a roll result to a target, and simply announces "Success" or "Failure"? What I understand as "nesting", but not what the wiki calls it. What i'm after is setting the macro up so that it rolls and completes itself, but then asks if I want to use another Macro. The system I'm using allows for rolls, but then you can add additional dice with various abilities, and I;d like to have something come up with the result asking "Would you like to use [the other macro]?" And that linking straightt o the use of the second macro. Thanks.

1. Dice Reference - Success Rolls 2. You can set up a macro that has an ' ability button ' link to a second macro, but the 'ability button' wouldn't be displayed conditionally. It would be displayed all the time as part of the result of the first macro.  You'll likely get someone who can help explain a bit more if you give more detail about what exactly you're trying to roll and display.
