    An invalid cast occurs when a source data type is being transformed into a destination data type but the conversion cannot take place because the data types are not compatible.  An example would be trying to transform a text string into a date/time.
    Any action that can do a conversion should be checked to make sure that the data going in is compatible with the data that is required to come out of the action.
