You have to set the ListIndex property as I indicated. If the list is not
sequential then you must get the index that corresponds to the value in the
UserProperty and supply that to the ListIndex property. If you are adding
items to the list then the first item you add is index 0 and so on. You
would have to compare each item as you add it to match it to your user value
and then get your current index value to supply to the ListIndex property.

Hi Ken

Again, thank you. You are assuming that my list of values has an
incremental
primary key, which is natural from the list I gave you. The primary key is
not incremental, so the ListIndex property won't work.

So let's say my list of values is:

Fred, 13
Jim, 4
Arnold, 54

These values are assigned to an array and the array assigned to the .list
property of myControl, which is a ComboBox. This all in the Item_Open()
function of the form.

When I use the form to enter an outlook item (it's a celendar item), the
ComboBox's .list property populates fine. I select Jim and myField's value
is
correctly set to 4. I close the item.

When I open it again, myControl has no value. I use MsgBox to display the
value and get an error because the value is null. Another control
(myControl2), just a Text Box, not a ComboBox, correctly displays the
value
of myField as 4, but try as I might I cannot assign the value 4 to the
ComboBox.

When I attempt to set myControl's value as follows:

myControl.value = 4

I get the error, "Could not set the Value property. Invalid property
value."

Why?

Thanks again for the help!
