Details

This message is generated when the right-hand side of an assignment to the values of a symbol includes an element that is not a rule.
This message is generated only by direct assignments to the values of a symbol.
Definitions are usually added using ordinary assignments, rather than using direct assignments to the values of a symbol.
Values stored in the internal structure of a symbol are represented using lists of rules.
Off[message] switches off the message; On[message] switches it on. For example: Off[DownValues::vrule].
