arcgis 10.0 - Expression labelling in ArcMap: Label only where value is > 1

I have a field in a shapefile with values ranging from 1-50 and multiple listed as 0. Is there a way to label only the features where the number in the priority field is > 0?

Answer

You can put this as the label expression for the feature:

def FindLabel([yourField]):
    if [yourField] is not None:
        if int([yourField]) > 0:
            return [yourField]
        else:
            return None

    else:
        return None

Using Python as the parser and checking the Advanced box.

Replace [yourField] with whatever field you are using to label.
