Again, if the triplets are an issue, you can just look at that chart. i.e. if you see what looks like an eighth note, and it's part of a triplet, it's a 12th note. If it looks like a quarter note, but it's part of a triplet, it's a sixth note. Etc. etc. etc.
Also, consider yourself lucky :'D
(also also, I guess saying N/A for a whole-note in a triplet isn't completely true. It'd be a 2/3rd of a measure in duration -- you'd have to use a 3&3 to show it though, since fractions don't work in mml :D)
