Duplicate alias in a SQL statement

Question

Hello Everyone!
I am getting an error "There is a duplicate table alias 'RAC4' in the FROM clause"
I did have the table with alias in the Data Environment, but I took it out and opened the table locally, no difference.
IF !USED("RAC2")
USE F:\Tv\TvWork Again ALIAS RAC2 IN 0 SHARED
ENDIF
IF !USED("RAC4")
USE F:\TV\tv_Billmaster Again ALIAS RAC4 IN 0 SHARED
ENDIF
IF !USED("RAC3")
USE F:\Tv\tv_billdetail Again ALIAS RC3 IN 0 SHARED
ENDIF
thisform.createrwcursor()
SELECT ;
RAC4.master_pk as Serial, RAC4.InvNo, RAC4.wono as Ref, RAC4.Bill_Date as InvDate,;
RAC4.grossamt as Total, RAC4.Discount, RAC4.billamt as Net, RAC4.scope as Work,;
RAC3.Description as Detail, RAC3.Qty, RAC3.Price, RAC2.usercode as Store;
FROM RAC4,RAC3,RAC2;
INNER Join RAC4 ON RAC2.wono = RAC4.wono ;
INNER JOIN RAC4 ON RAC3.wono = RAC4.wono ;
Where RAC2.Client = "09RC01";
AND Between(RAC2.invDate,ldBegin,ldEnd);
INTO CURSOR RAC5;
ORDER BY RAC4.InvNo
I can't figure it out....any ideas?
Thanks again!

I can't believe this.....I changed everything.....read a bunch to fully understand what you were saying and the thing still won't work.
I actually went to the extreme of pulling out the SQL statement and putting it into a separate program so it is easier for me to test........it still won't work.
I am getting an error message of "SQL Column WONO isn't found" I double checked the select statement itself, I checked the Tables and it exists in each, character (7) in each.
LOCAL ldbegin,ldend
ldbegin = "03/02/2015"
lend = "03/30/2015"
SET DEFAULT to F:\TV\
OPEN DATABASE TV.dbc
SELECT TV_BILLMASTER.Master_pk as Serial,TV_BILLMASTER.Invno,TV_BILLMASTER.WONO as Ref,;
TV_BILLMASTER.Bill_date as InvDate,TVwork.usercode as Store,TV_BILLDETAIL.Descr as Detail,;
TV_Billdetail.QTY,TV_BillDetail.Price,TV_BILLMASTER.Grossamt as Total,TV_BILLMASTER.Discount,;
TV_BILLMASTER.Billamt as Net,TV_BILLMASTER.Scope as Work;
FROM TV!TVWORK TVWORK INNER JOIN (TV!TV_BILLDETAIL TV_BILLDETAIL INNER JOIN TV!TV_BILLMASTER TV_BILLMASTER ON TVWORK.WONO = TV_BILLMASTER.WONO) ON TV_BILLMASTER.wono = TV_BILLDETAIL.wono;
WHERE (TVWORK.CLIENT='09RC03'AND BETWEEN(TVWORK.INVDATE,ldbegin,ldend)) AND TVWORK.wotype<'5';
INTO CURSOR RAC5;
ORDER BY TV_BILLMASTER.Invno
BROWSE
return
After testing and testing...I took out the alias names and just went with the actual table names....
Now......while I was testing this..I wanted to be sure of the error message so I went and ran it again....and I got a blank browse window......it worked but didn't get any records.....it should have gotten 200.
I have been messing with this simple little SQL statement for 3 days.
what am I missing?
