Index a TableDef in order to seek through table files

[GIJoeFigure]

Hello. I have been trying for the longest time to set up a table of computer folder pathways like "C:\Tmp\bin" and other data columns using TableDef and CreateField lines. That part now works fine but I would like to take this new table and index a field so I can use the Seek function to find if files exist in each pathway in the table. I keep getting an error saying that "pathway" is not an index. Please help.

I forgot to mention, I have been trying this by creating the fields, appending the tabledef, then opening the recordset by the same name. The recordset always has trouble with setting index
