datagrid

I have been working with the enhance search widget for a while and so far everyone seems to like it.....I am now adding a datagrid to the fray. Easily completed the setup in the config...there is a widget tab at bottom of screen.. In the eSearch.xml, I have added
gridfield="true" to the fields tag for the fields I would like to see in the datagrid, as shown in documentation.

after a successful search, the results are not being populated into the datagrid. Though I have read and reread the documentation, I know I am missing something (probably basic) in getting the successful search results to populate in the datagrid. any hints or suggestions would be appreciated.

thanks
