Percent Problem

I have a field that I am using for percent column section, If the field has a value in it then it would show the value as a percent, but If the field has no value I do not want anything to show up in the column including the percent sign. So far I can not get the view just to show nothing. In the column where no value has been enter it % sign or a zero.

The field on the form is a Dialog List where the user gets the numbers from

Thanks in advance for any help
