ComboBox.Value Property (Access)
Determines or specifies which value or option in the combo box is selected. Read/write Variant.
The Value property is set to the text in the text box portion of the control. This may or may not be the same as the setting for the Text property of the control. The current setting for the Text property is what is displayed in the text box portion of the combo box; the Value property is set to the Text property setting only after this text is saved.
The Value property returns or sets a control's default property, which is the property that is assumed when you don't explicitly specify a property name.
The Value property is not the same as the DefaultValue property, which specifies the value that a property is assigned when a new record is created.
