>>>I wonder if there is a way to use a combobox that also allows free text entry? The list has different values from an array, but if I enter a text that is not found in the list it blanks out on Lostfocus.

Yes, Christian, you could do that. Just remember that you can trap the situation where user inserted something not part of the list by .Value being empty, and .DisplayValue being not empty.

This is a simple way of dealing with this, while the combobox is bound to a control source. As soon as the user inserts a new value, it becomes part of the list. Hence, its value can now set the control's .Value property, which, in turn, will populate the control source.
