JQuery Validation Error on Checkboxes

JQuery Validation Error on Checkboxes

I have the following code on my form.

<input name="requiredCheck2" type="checkbox" id="requiredCheck2" value="1" class="required" title="Checkbox Required" style="margin-left: 152px; margin-top: 5px" />

When the submit button is clicked the error message is correctly displayed.  However, if I keep clicking on the submit button the message is repeated again and again and breaks my layout.  Normally it is only ever shown once so I dont know what the issue is.  Also, if i click the checkbox the error message does not go away.

Could use some help figuring this out.  Thanks
