Center a field

I have read every tutorial on your site and tried everything I can think of and I still can not center this field. http://form.jotform.us/form/51884935448167

Please Help,

Thanks

Hi,

To adjust the margin for the Zipcode field, add this code to your form:

#id_4 {
    margin-left : 150px;
}

Adjust the value until your field in positioned how you would like it.  The code entered above will make your form look like this:

If you have any further questions, let us know and we will be happy to help.

Thank you, that worked for the field itself, but what about the label? 

To center adjust the label positioning, try this code:

#label_4 {
 margin-left: -20px;  
}

Updated form with new code added:
