Using 1.07.2 version of PHPFormMail which I have modified to incorporate reCapatcha. All working well except that generated email include the recapatcha_challege_code, the recapatcha response, and the value of the submit button. Even with a clean version still get the value of the submit button included. Any ideas on how to stop this happening?

Since PHP FormMail is a non CoffeeCup product, it is not very likely that you will get an answer to your problems in this forum. Your best bet is to check if there is a forum at the producer's website and ask your questions there.

CoffeeCup has its own web form application which you can find here: http://www.coffeecup.com/form-builder/
