Sign out of yahoo and try a different browser since this is
a widespread glitch..Otherwise you used too many words.
There is a limit.

Type your heading/ question in the box, ignore, `Details` and press, `Expand` instead,
then you have the space you need upon the resulting page,,

Your poem is too long, by however many characters are in the red box with the negative.
