In "Define Data Link Search" Table Field select should be a drop down list of available fields

In "Define Data Link Search" Table Field select should be a drop down list of the search table fields, not a free form text box.  By making it a drop down list, similar to the Feature Field select, it would remove the risk of mis-typing the desired table field.

The drop down list is available elsewhere and this is a great location to implement it as well.
