This is my functions.php. I have added the custom checkbox using the above code present in your github. But i am not able to display a danamojo donate button after clicking the checkbox. It should display it in donation receipt after submitting and should also save in database. For example, if a user or donor is an Indian, then he will check the checkbox and then the button will gets displayed below the checkbox. Then he will pay the donation amount. After that the donation amount and the Indian value in the checkbox should be saved and displayed in the donation receipt. The checkbox should be added after phone number text box. Thank you.
  
  
  

This is the screenshot. I have added a checkbox called Indian and when i click that it should display a danamojo donation button and the value of checkbox "Indian" should be saved in database and should be displayed in the receipt form after submitting the donation.Please help me in solving this issue. Thank you.
