There should be a space before the 'o', i, e, ' o'
Making that change it works fine for me. From the position of the caret

There is no such thing as a niladic verb in J. If you type the name of
a verb, Roger types its definition. There is no way to write a single
word that produces different results when you repeat it.
toss'' is as close as you get.
