Short Answer: dont put quotes around the numbers
Longer Answer:
Quotes (standardly in most scripting or programming languages, and here also) are used to say "the next item might be more than one word" and it usuall seperates items by a space. So the quotes tell the program not to not skip ahead too quick.
In other words:
units 30 1085 does not need quotes because it reads it 1 2 3
but #comname "Fir the Frozen" would need quotes so that read items 1 2 wont stop at Fir, but include the whole Fir the Frozen into item 2
edit: Sombre beat me to an answer. Darn my "teaching mode"
