To populate check mark or X in checkbox field in PDF

Question

Hi, 
 I have a form which has the checkboxes. I have a screen to capture the inputs of the form from user where I am using multiple checkbox field to capture an answer. Then I need to generate the PDF of that form. I am facing the challenge to fill the tick mark or X in the box in the checkbox field in PDF. How can I accomplish this? Any help? 
 
 Thanks, 
 Brinda Sateesh

You have to edit the export value in Adobe to use the word "Yes". Then in Appian, pass 0 or 1 as a boolean to check it.

In the most recent PDF i built, when using the "Fill PDF" smart service (which i recommend since it allows you to pass in an expression to contain the values, instead of filling them out one-by-one in the clunky older node setup), after some experimentation I discovered that the checkboxes only worked when I passed values of "Yes" and "Off". I don't remember whether the "unchecked" condition required "Off" or just anything other than "Yes" to be unchecked, but the "filled" condition definitely required a text value of "Yes". Note, though, that this might depend on the particular configuration of the particular checkboxes in your PDF template.
