this step is wrong. What you need is a word. There are two possibilites:
1) *Not* converting a string:
a-word: 'n2
2) Converting a string:
a-word: to word! trim "n2 "
Notice I didn't need REDUCE at all (important) and I didn't need #"'"
either. Moreover, notice I trimmed the string to leave out space.

Here is what you get:
a-word: 'n2 ; == n2
mold a-word ; == "n2"
b-word: to word! "'n2 "
mold b-word ; == "'n2 " (notice the difference!)

You are welcome.
