Hi Ashley,
>> The Locator would be ideal but it only works on the default sort field,
no, it can work on a list of fields in the table (whether they are columns in the browse or not.)
and if the browse is blank you cannot click on the header because there is none. See the "Locate on Fields" setting on the "Sort" tab for a column. You can enter a comma-separated-list of fields here.
Cheers
Bruce
