>I was wondering if there is a way to programmatically cause a combo box to open based on validating data entered. What I want to do is perform a check of the data entry against the query/table in which the value which populates my combo box extist, and if that value does not match, have the combo box open automatically, presenting the list of choices for data entry. Can this be done?

You could use this:

thisform.mycombo.setfocus()
keyboard "{Alt+DnArrow}"

You might want to somehow let the user know that the value is incorrect before this otherwise it might be seen as a bug.
