Auto-expand Word FormField Dropdown/Combobox

[ACH381]

I'm runing an entry script on a dropdown type formfield in Word that automatically expands the dropdown when the field is selected & the value of the field is 1. I don't want to expand the field if the user has been in the field before and has selected a value other than the first blank value. I have the first option set to blank spaces so it displays as blank until one of the other options is chosen. If I just use the sendkeys command the "auto-dropdown" works fine. However, when I test the value with the If-Then statement the sendkeys command does not work. Here is the script. Any ideas?

Sub ExpandDropdown()
If ActiveDocument.FormFields("FF1").DropDown.Value > 1 Then Exit Sub

SendKeys "%{Down}"
End Sub
