# Examples

on deleteField -- first save the contents in a custom property set the uFieldText[the short name of the target] \ of this card to the text of the target pass deleteField end deleteField

# Description

Handle the deleteField message if you want to perform cleanup before a field is removed from the stack.

The actual deletion is not triggered by the deleteField message, so trap the message and not allowing it to pass does not prevent the field from being removed.

However, the undo command will restore a field after it is deleted by the user. For example, the following handler, placed in a card or stack script, effectively prevents a field from being deleted by the user:

on deleteField beep send "undo" to this card in 5 milliseconds end deleteField
