>All I want to know is how to update the listbox contents whenever it changes whether I am on this form or another form and return to this form.
>When I leave the form and add some records to atts and come back to the form it does not update the listbox unless I press Prev or Next button first. Any ideas what's wrong? Is there are better way to do this? I tried THISFORM.lstTube_tries.Requery and DODEFAULT(), but then the listbox refreshes, but other controls on the form disappear. Thanks for the help.

Make sure, that the form's main table is selected. Also you may surround your manipulations with thisform.lockscreen = .t. / .f.
