How to summarize (prevoius function)

25 Views

hi expert,

is there a way on how to summarize the previous function in crystal report

on details

Numatcard U_40STD

1234 2

1234 2

1234 2

--------------------------------------

output

If ({OINV.NumAtCard} = previous({OINV.NumAtCard})) then 0 else {OINV.U_40STD}

2

0

0

----------------

footer - SUM here should be 2

Note i need to summarize this the whole detail so that later on i want to use this on CrossTab

Thank you

regards
