It looks like there is a problem with the checkboxes. Did you set the checkboxes dynamically after you added the form? The code that is set for the making the box checked is incomplete.
Did you update an existing form? If so please post back with that form before adding Form Builder to it. It looks like the checkbox is set to dynamically be checked based on a compared to value but the comparison is not happening correctly. Would you like the boxes to be checked automatically under any circumstances?
