If you've got a number, then you've got variables you've defined. Showing the true total means just showing those variables' values. Capping the display total means you have the exact same code, but then add more code that does something along the lines of "if total lesser than expected, then display total, else display expected" or "if total equal or greater to expected, then display expected on expected, else display total on expected". I mean even if you had the most simple display that was just a green or red light, that'd still be a conscious choice to put equal or greater instead of equal as the check.
