Ms sql - {"The referenced table must have a primary or candidate key. [ FK Name = ForeignKeyB_Details ]"}

Question

I have a txt file which has all the sqltext in it separated by semi colon .Then I try to run a query one by one like this-
            var conn = new SqlCeConnection(ConnectionString);
            conn.Open();
            var cmdArray = Regex.Split(sqlText, ";");
            var cmd = new SqlCeCommand(null, conn);
            foreach (var text in cmdArray)
                cmd.CommandText = text;
                if (!text.Equals(string.Empty))
                    cmd.ExecuteNonQuery();
                else
                    break;
            conn.Close();
I get the error {"The referenced table must have a primary or candidate key. [ FK Name = ForeignKeyB_Details  ]"}
here is part of my txt file-
CREATE TABLE A
       PrimaryId nvarchar(10) NOT NULL REFERENCES C(PrimaryId),
       UserId nvarchar(20) NOT NULL,
       FirstName nvarchar(30) NOT NULL,
       MiddleInitial nvarchar(1) NULL,
       LastName nvarchar(30) NOT NULL,
       MobileNumber nvarchar(20) NULL,
       PhoneNumber nvarchar(10) NOT NULL,
       PhoneExtension nvarchar(6) NULL,
       FaxNumber nvarchar(20) NULL,
       EmailAddress nvarchar(50) NOT NULL,
  CONSTRAINT PrimaryKeyA PRIMARY KEY(PrimaryId, UserId)
CREATE TABLE B(
   MarketId int NOT NULL references E(MarketId),
   UserId nvarchar(20) NOT NULL,
   UserFirstName nvarchar(30) NOT NULL,
   UserMiddleInitial nvarchar(1) NOT NULL,
   UserLastName nvarchar(30) NOT NULL,
   PhoneNbr nvarchar(10) NOT NULL,
   Extension nvarchar(6) NOT NULL,
   FaxNbr nvarchar(20) NOT NULL,
   Email nvarchar(50) NOT NULL,
   ShortName nvarchar(10) NOT NULL,
PublicIdFlag nvarchar(6) NOT NULL references D(publicId),
        CONSTRAINT PrimaryKeyB PRIMARY KEY( MarketId, UserId)
ALTER TABLE B ADD CONSTRAINT ForeignKeyB_Details FOREIGN KEY(UserId, UserFirstName, UserMiddleInitial, UserLastName, PhoneNbr, Extension, FaxNbr, Email) REFERENCES A(UserId, FirstName, MiddleInitial, LastName, PhoneNumber, PhoneExtension, FaxNumber, EmailAddress);

Hi,
Foreign key columns are frequently used in join criteria when the data from related tables is combined in queries by matching the column or columns in the FOREIGN KEY constraint of one table with the primary or unique key column or columns in the other table.
For more information about the foreign key constraint, please refer to this link:
