Try and Catch will always work :) But if you want a different, 'more elegent' solution...
Is the problem that some 'ProductInformation' elements do not contain all the expected sub-elements? i.e. you are expecting: productinfo[x].productid productinfo[x].productLink productinfo[x].productName And sometimes you only get: productinfo[x].productid productinfo[x].productName If so, I imagine you want to display a record even if it does not contain all the correct fields and instead of try & catch you should be able to use <cfif StructKeyExists(productinfo[x], 'productLink')>Show it</cfif> But maybe I'm still getting the wrong end of the stick?
