Add captcha code to insightly web to contact form

I need to edit my web to contact form that was generated through the INSIGHTLY CRM to inlclude a captcha or some sort of spam filter. I have been getting a few quality leads but WAY TOO MANY SPAM LEADS!!! please help! this is my contact form code. I use a CRM called Insightly that generated this code for me to use on web to contact forms. Insightly doesnt contain any sort of captcha system so I am attemting to add the code for a captcha widget that I added to the wordpress page. Long story short I need to manually apply the code for the widget, to the code that was provided by my crm "web to contact code" The instructions to place the capthca within my "web to contact code" are: I would like to add Captcha to the custom form on my website. How can I do this? Install the Captcha plugin and activate it. Open the file with the form (where you would like to add captcha to). Find a place to insert the code for the captcha output. Insert the necessary lines: if( function_exists( 'cptch_display_captcha_custom' ) ) { echo "<input type='hidden' name='cntctfrm_contact_action' value='true' />"; echo cptch_display_captcha_custom() } ; If the form is HTML you should insert the line with the PHP tags: <?php if( function_exists( 'cptch_display_captcha_custom' ) ) { echo "<input type='hidden' name='cntctfrm_contact_action' value='true' />"; echo cptch_display_captcha_custom(); } ?> Then you should add the lines to the function of the entered data checking and my web to contact code is: <form name="insightly_web_to_contact" action="[login to view URL]" method="post"><input type="hidden" name="formId" value="4KkOIq35MJ4f/NpMmoi8Nw=="/><label for="insightly_firstName">First Name: </label><input id="insightly_firstName" name="FirstName" type="text"/><br/><label for="insightly_lastName">Last Name: </label><input id="insightly_lastName" name="LastName" type="text"/><br/><label for="insightly_organization">Organization: </label><input id="insightly_organization" name="Organization" type="text"/><br/><label for="insightly_role">Title: </label><input id="insightly_role" name="Role" type="text"/><br/><input type="hidden" name="emails[0].Label" value="Work"/><label for="email[0]_Value">Work Email: </label><input id="emails[0]_Value" name="emails[0].Value" type="text"/><br/><input type="hidden" name="phones[0].Label" value="Work"/><label for="phones[0]_Value">Work Phone: </label><input id="phones[0]_Value" name="phones[0].Value" type="text"/><br/><label for="insightly_background">Additional background information: </label><br><textarea id="insightly_background" name="background"></textarea><br/><input type="submit" value="Submit"/></form> The issue I am having is that I don't completely understand the options its providing in the instructions. Sounds like I need to identify if this "web to contact code is html or some other variation of coding? And then place the captcha code into the contact form
