EnterField (windowRef, fieldNameString, fieldValueString)

A script handler you can implement to override standard MoneyWorks behaviour.

Automatically called:  When a field becomes active by being tabbed into or clicked.

Use for:  Preflighting a field (maybe to save the contents before the user changes them).

Return value:  ignored

Specific Naming You can and should implement an EnterField handler that is specific to the particular window ID and itemID of interest. e.g. EnterField:<WindowId>:ItemID:<TransactionType> (the last of these applies only when the WindowID is F_TRANS)
