Repeat Line

Hi all
I am new in the forum and in SQL
I have this code

Code:

SELECT
PersPlac.Name,
Zoom1.Descr,
Client.PersonID,
Client.Name AS CLIENT_NAME,ClientCu.Period,ClientCu.YearID,IVPeriod.PrdDescr,(ClientCu.DebitP/((InvVAT.VATVal+100)/100)),InvVAT.VATVal
FROM Client
RIGHT JOIN Salesman WITH (READUNCOMMITTED)
ON (Client.SalesmanAA = Salesman.AA)
LEFT JOIN PersPlac WITH (READUNCOMMITTED)
ON (Client.Place = PersPlac.Code)
LEFT JOIN Zoom1 WITH (READUNCOMMITTED)
ON (Client.Zoom1 = Zoom1.ID)
LEFT JOIN CLIENTCU WITH (READUNCOMMITTED)
ON (CLIENT.PERSONID=CLIENTCU.PERSONID)
RIGHT JOIN InvVAT WITH (READUNCOMMITTED)
ON (CLIENT.TAXCAT=InvVAT.TAXCAT)
RIGHT JOIN IVPeriod WITH (READUNCOMMITTED)
ON (ClientCu.Period = IVPeriod.PeriodID)
WHERE Salesman.Name='ΚΟΡΜΠΟΣ ΦΩΤΙΟΣ'
AND ClientCu.Period<>0
AND PersPlac.Name<>'Εικονική Γεωγρ. Περιοχή'
AND Client.Name='ΦΩΤΕΙΝΙΑ ΑΝΝΑ'
and InvVAT.VATVal in (13,19)



the code run fine but every line is turn back 4 times.
Why?

Thanks for the help
