Using Umbraco 7, I hace setup a macroscript partial. It seems to work fine, however if I have a "metaDescription" for a returned result that is null, then the macro doesn't render correctly and gives an error.

If the results all have metaDescriptions then all is good, but I need to add an if statement or some logic to let the results to not display that field if Null or no value...All the various if statement syntax I try don't seem to work though..Any ideas?

Thanks!
