Donald,
As the others have said the Index on statement should use the Tag option so that the index is deleted with the cursor. Assuming the no other indexes are set up in other places in your code then the interactive change should use the correct index. I prefer to specify both the table and the index that way when I'm reading through my code I know exactly what is being searched for (especially here where the index order is being set in a different method).

INDEX ON ti_num TAG ti_num

=SEEK(.txtSrch.value, "DD_TASKINFOGrd", "ti_num")

but hey that's just my preference.
