The checkbox isn't working

Even if I tick the checkbox, it will input a null value into the database.

I think you have tried to deconstruct an 'answer' variable from the incoming data in your postStatement query, but it is sending through a 'boolean' variable instead.

Do you want your checkbox to be true by default? If you do, you will also need to make sure that its 'checked' property is set to true (this will set what the checkbox looks like by default).
