Google Captcha integration into Magic Action Box

Hi,
I am having a problem integrating Google Captcha into Magic Action Box.
The sign up form raw code is coming form Intouch CRM and when processed in MAB, it gets rid of the part of the code that addresses Captcha (it’s in the form of script). Then I put it in the processed code anyway and that displays Captcha as required but then I can complete the sign up form without selecting ‘I am not robot’.
Can anyone help? Thanks in advance.
