I want to be able to calculate the length of a speech I am writing using the NUMWORDS function. To do this, I want to take the number of words in my document and divide by 190 (the number of words spoken per minute).

I'm trying to do so using a table in the footer of my document:

7/28/2017 1:49 PM 3,822 { =B1/190 } Revision: 123

In the table, A1 is date and time of last revision, B1 is the number of words (using the NUMWORDS field code), C1 is the formula I am trying to do to calculate speech duration, and D1 is the Revision #.

The formula I enter just sits there and does not evaluate. Any tips? Thanks!
