When a collection gets filtered, the filter function is applied to each item of a collection separately. So the passed parameter for the filter function is always an item of your collection. In your case the collection contains strings. The filter function receives the string, all you have to do in the function is to compare it to your filterText string. To do that Josh casted the passed parameter as a string to compare it to the filterText variable. -- david keutgens software consultant cynergy australia web | http://www.cynergysystems.com.au
