How do I assign values to several variables in a sql select statement

I created a trigger and need to assign values to multiple variabes. I am getting errors when I execute the statement.

I get the following error
Msg 156, Level 15, State 1, Procedure Update_Payments, Line 19
Incorrect syntax near the keyword 'Select'.
Msg 156, Level 15, State 1, Procedure Update_Payments, Line 26
Incorrect syntax near the keyword 'from'.


What am I doing wrong here?


--SCRIPT



CREATE TRIGGER Update_Payments
ON  Sales AFTER INSERT
AS
BEGIN
DECLARE @CurrentOrderID int
DECLARE @CurrentPublisherID [char](10)
DECLARE @CurrentISBN [char](20)
DECLARE @CurrentContactID [char](10)
DECLARE @CurrentDate datetime
DECLARE @RoyaltyAmount money

SET NOCOUNT ON;

SET @CurrentOrderID = Select MAX(OrderID) from Sales

Select @CurrentPublisherID = P.PubisherID,
         @CurrentISBN = S.ISBN,
         @CurrentContactID = R.ContactID,
         @RoyaltyAmount = S.SaleAmount * R.rate/100,
       @CurrentDate = S.Date,
         from Publishers P,Sales S,Royalty R where SOrderID = @CurrentOrderID
                          and S.ISBN = Publishers.ISBN and R.ISBN = S.ISBN

Insert into payments Values(@CurrentPublisherID,@CurrentISBN,@CurrentContactID,@RoyaltyAmount,@CurrentDate,'Scheduled')
                           
SET NOCOUNT OFF;  

END
GO

i think it might be this:

SET @CurrentOrderID = Select MAX(OrderID) from Sales

try

SET @CurrentOrderID = (Select MAX(OrderID) from Sales)

or simply

Select  @CurrentOrderID =  MAX(OrderID) from Sales

on your @CurrentDate = S.Date line, you need to remove the  comma

Please don't take it the wrong way, but let me suggest you read up on TRIGGERs and in particular the INSERTED logical tables.
