Crystal Report: Display 0.00 for duplicate values

Question

I am making a crystal report which displays values from database. Now the values from db contains duplicate values.

I need that duplicate values should be suppressed and

Answer 1

Do not check Suppress if Duplicated.. You need to write formula for Display String.

For example,

if PreviousIsNull ({object.field}) then 
  cstr({object.field})
else
if CurrentFieldValue=previous({object.field}) then 
   '0.00' 
else 
  cstr({object.field})

EDIT:

  if PreviousIsNull ({object.field}) then 
      cstr({object.field})
    else
    if {object.field}=previous({object.field}) then 
       '0.00' 
    else 
      cstr({object.field})
