When I manually enter responses, I am able to enter information into most fields. The only ones I am having a problem with are the 4 checkboxes that I have marked as required. I receive the error "This value does not match this column's type. Please enter a checkbox." there is not a box to click in and I'm not sure how to insert one. I have entered an X in the image below to recreate the error...hoping someone can help. Thanks.
