good/bad rep change

[Shinobi]

Im talking about the rep thing that comes with 3.0.3 here:

is there any way to make the text of the rep meter change depending on whether its good or bad. For instance:

Is a users rep is 15 the postbit says Good Rep: (and then the green bars)

but if they have a negative rep of -15 the postbit says: Bad Rep: (and then the red bars)

i dont know much about php but isnt there a place where u can do and if else statement and make it write out different words depending on if the rep is below or above 0
