I have a "Searchfield" Textbox in my form, which is used to filter data on the form. The filter executes after Update and I would like to have access return to the "Searchfield" Textbox highlight what was previously enter and ready to enter in difference search criteria without using to delete key to erase the pervious criteria.

Set focus to the field that you want to return to, i.e., Me!SearchField.setfocus.

If you're on a different subform, you have to set focus to the subform or form that you want to be on first - use the expression bulder for that, it's easier.
