I need to find the grade level score for a document that should be at a
Kindergarten level. When i check the document, it comes out Flesch-Kincaid of
0.0. (Other documents of this type I've checked come out numbers such as 0.7
for the reading level.)

Any idea how I can get it to give me a reading? I have reset the grammar and
spelling check to recheck the document, but it makes no difference.

Thanks!
