Rick,

You can also test for null or undefined rather than trigger an error. I usually do it like this:

var doc = app.activeDocument;  
var xrefFmt = getXRefFmt(doc,'Hoffman Accessory');  
alert(xrefFmt.name); 

function getXRefFmt(doc,formatName) {  
  var xrefFmt = null;  
  xrefFmt = doc.crossReferenceFormats.item(formatName);  
  if (xrefFmt == null) {  
    xrefFmt = doc.crossReferenceFormats.add({name:formatName});  
    xrefFmt.buildingBlocks.add({blockType:BuildingBlockTypes.FULL_PARAGRAPH_BUILDING_BLOCK});  
    xrefFmt.buildingBlocks.add({blockType:BuildingBlockTypes.CUSTOM_STRING_BUILDING_BLOCK,customText:', page '});  
    xrefFmt.buildingBlocks.add({blockType:BuildingBlockTypes.PAGE_NUMBER_BUILDING_BLOCK});  
  }  
  return xrefFmt;  
}
