How can I count words (or syllables) on the text that my client is writing?

Hi Friendly support team!!

I need to make a form where my clients can write their own script for their animated videos. The form has 5 parts where they have to write about their target public, problem, solution, success and call to action.

I don´t want to limit the amount of words that they use. Instead, I want to be able to count the words on the 5 parts and tell them how long their voice over will be and how much their video will cost.

We do not currently have a feature that would allow you to calculate the total number of words in text fields.  There is a possible workaround in the following thread: http://www.jotform.com/answers/466451-How-can-I-retrieve-word-count-from-a-text-area-for-calculation.

With more discussion about it here:

But it does require using the full source code of the form and adding a bit of code to the page the form is embedded to.
