I want to put a checkbox image in my list I am using this fo the CSS but it is not correct.

ul.hiddenbullet {

text-decoration: none;
background-color: #FFFFFF;
text-indent: 15px;
list-style-position: outside;
list-style-image: url(/CBO/images/ckbox.jpg);
padding: 6px;
margin: 2px;

I want it to look like this: There will be a checkbox by each of the responses.

1. I am satisfied with the New Employee Orientation (NEO) I received.
Strongly Agree
Neither Agree or Disagree
Strongly Disagree
Not Applicable

Any suggestions would be great.
