Subject: SQL consundrum du jour...
Greetings... 
I've used this exact same SQL in other updates just fine...all I sub'd this time was the file(s) and field(s)...yeah, famous last words...  But this time I'm getting a "Null values not allowed in column or variable MSALES. "  error...  Any idea what I'm not seeing? 
msales and rep are saleman numbers, and mcusno and cust are customer numbers...  
update drtemp.master                                            
 set                                                            
   drtemp.master.msales =                                       
(select                                                         
    rep     from                                                
           drtemp.slsupd                                        
               where                                            
              (drtemp.master.mcusno = drtemp.slsupd.cust   )    
    )      
Thanks...
