Hi

if "Required" property of your list istem is "NO", Clear_list built-in clears all list items. But if it is "YES", it does not clear current label. So first set "Required" property to "NO" then clear list.

Set_Item_Property('MYLISTITEM', REQUIRED, PROPERTY_FALSE);
Clear_List('MYLISTITEM');

regards.

Hi,

set "Initial Value" property of your list item to NULL during design time (If you need an initial value, assign it in when-new-form-instance trigger)

regards
----------------------
For a Poplist or T-list-style list item, CLEAR_LIST will not clear the default value element or the other values element from the list if they do not meet the criteria specified for deleting these elements with DELETE_LIST_ELEMENT.

When either the default value or other values element cannot be deleted, CLEAR_LIST leaves these elements in the list and clears all other elements. Refer to the restrictions on DELETE_LIST_ELEMENT for more information.
