Added a New Field to an Index

I added a field to a table index.  The added field is not recognized as a part of the index to fetch the record when select is clicked from the row exit to go from a find/browse form to a fix/inspect form.  I tried creating a new fix/inspect form.  The initial fields of the index appeared in the data structure of the form but not the field that was added.  How do I make the added field recognized?
