Updating a table variable

DECLARE @days Per Email TABLE ( Vendor Id INT, Days Per Email SMALLINT, Last Email Date DATE, Prod Id INT ) INSERT INTO @days Per Email (Vendor Id, Days Per Email, Last Email Date, Prod Id) VALUES (78, 5, NULL, 2), (78, 3, NULL, 387), (78, 1, NULL, 295); UPDATE @days Per Email SET Last Email Date = (SELECT MAX(Action Date) FROM User Actions Report WHERE Product Id = Prod Id AND Action Type Id = 2); UPDATE X SET Last Email Date = Z.

I'm declaring the variable @Current Table and inserting into it using a SELECT statement with no problems.I changed the name to Prod Id, which does not exist in any of the tables involved in UPDATE query.
