When you click an item in a list box or a combo box control, the macro that you assigned to the list box or combo box fails to run.

This behavior occurs when the following conditions are true:

  -and-
• You assign a macro to the list box or combo box.
  
  -and-
  • The item you click in the list box or combo box is the only item in the control.
    
    -or-
  • You consecutively click the same item in the list box or combo box. (That is, the currently selected item is not changed).

Method 1

Make sure that the list box or combo box contains at least two items, and that you select an item that is different from the currently selected item.

Method 2

When you format the list box control (double-click the list box), under Selection type, click Extend or Multi. These selection types allow the macro to detect a change in the status of the list box.

NOTE: This applies only to the list box control. The combo box control does not have a Selection type property.

Method 3

Set or reset the ListIndex property to 0 (zero). For example, use the following line of code:

A list box can run a macro based on the changes that occur in that list box. When you select an item that is different from the current selection, a single or extended list box is changed. Therefore, if the list box contains only one item, or if you reselect the same item, the macro does not run.
