I hav a prob like this

Itemcasc and Itemcascaddition a are 2 sub reports

Itemcasc formula contains like this,

DIM str AS STRING

IF {ItemCASCProduct.CASCProductCode} <> "" THEN
    str = str + "CASC Product Code         : " + {ItemCASCProduct.CASCProductCode} + CHR(13)
END IF

Itemcascaddition formula contains like this,

DIM str AS STRING
IF {ItemCASCAddition.CASCCodeOne} <> "" THEN
    str = str + "CASC Code One             : " + {ItemCASCAddition.CASCCodeOne} + CHR (13)
END IF
IF {ItemCASCAddition.CASCCodeTwo} <> "" THEN
    str = str + "CASC Code Two             : " + {ItemCASCAddition.CASCCodeTwo} + CHR (13)
END IF
IF {ItemCASCAddition.CASCCodeThree} <> "" THEN
    str = str + "CASC Code Three           : " + {ItemCASCAddition.CASCCodeThree} + CHR (13)
END IF
FORMULA = str

i ll show my xml data.

  </cbc:ItemCASCAddition>

i write inside section report inside Itemcascaddition suppress(no drill) x-2 like this  

{ItemCASCAddition.SequenceNumber}=previous ({ItemCASCAddition.SequenceNumber})

but my output shows like this

CASC Product Code:VBAOBC

CASC Code One    :CODE1A
CASC Code two    :CODE1A
CASC Code three    :CODE1A

CASC Code One    :CODE1BA
CASC Code two    :CODE1BA
CASC Code three    :CODE1BA

CASC Product Code:VBAVBA

CASC Code One    :CODE1A
CASC Code two    :CODE1A
CASC Code three    :CODE1A

CASC Code One    :code1BA
CASC Code two    :code1BA
CASC Code three    :code1BA
 
BUT IT SHOLULD SHOW LIKE THIS

CASC Product Code:VBAOBC

CASC Code One    :CODE1A
CASC Code two    :CODE1A
CASC Code three    :CODE1A

CASC Code One    :CODE1B
CASC Code two    :CODE1B
CASC Code three    :CODE1B

CASC Product Code:VBAVBA

CASC Code One    :CODE1BA
CASC Code two    :CODE1BA
CASC Code three    :CODE1BA

CASC Code One    :CODE1BB
CASC Code two    :CODE1BB
CASC Code three    :CODE1BB

I KNOW ITZ COZ OF {ItemCASCAddition.SequenceNumber}=previous ({ItemCASCAddition.SequenceNumber}) FORMULA PROB INSIDE Itemcascaddition  X-2
Cn u help me 2 rewrite err free formula?

thanx in advance
