The checkbox option is greyed out, and I can't add it to my document. What should I do?

All checkboxes must be associated with a signature to ensure the integrity of the document. To enable the checkbox function, select the party you'd like to take the action, and drag the signature icon onto the page where you would like them to sign. Once you've done this, you'll notice that the text box and checkbox icons are now available. Drag the desired icon over to the form.
