Character Count And Characters Remaining for Formidable Forms Plugin

General information for the website: Real Estate Website
Kind of development: Customization of existing website
Description of requirements/features: We have 7 forms on our website http://www.pghfoh.com/ and we are using premium version of Formidable - https://formidablepro.com

We want to limit characters on any paragraph text model to 525 characters and also show the user how many characters that they have typed so they know how many that they have left.

All forms will be the same, so we basically need code to add to site that will enable this functionality in the Wordpress Plugin.

We basically need someone to write code and email us details and where to implement and we can add to site.

Here is code from their website that could work for one part, just need it updated to our specs: https://formidablepro.com/knowledgebase/frm_validate_field_entry/#kb-minimum-word-count

Let us know if you need more details, etc.
