  A String Required

  Aug 30, 2012 05:56 AM|sandston|LINK

  I am quite a newbie to Crystal Reports so bear with me if I do not provide all the relevant information first off. 
  
  Below is my formula: 
  
  if {?ARR_DEP} = "A" then 
  {FLIGHTD_ALL.ACTUAL} 
  else 
  if {FLIGHTD_ALL.CANCEL_CODE} = "C" then 
  "" 
  else 
  {FLIGHTD_ALL.OFFCHOCKS} 
  
  when I attempt to validate the formula advises me that a sring is required. 
  
  Any advice or guidance would be much appreciated.

  You have nested if/else blocks but the outer one is incomplete.

  Hi,
  
  Kindly check the DataType for all mentioned below ,
  it may be possibility that data might be string & you are referring it as integer,
  
  ARR_DEP
  FLIGHTD_ALL.CANCEL_CODE
  FLIGHTD_ALL.OFFCHOCKS
  
  While comparing please check whether is it String or Numeric / Integers
  
  

  Hope this will work for you.

  If this post answered your question or solved your problem, please Mark it as Answer.
  
  
  //Happy Coding
  
  Regards,
  RajeshS.

  Hey Dan, 

  Thank you for the response, I understand vaguely is there an easy way around resolving the last incomplete nested if/else statement.

  Hi Rajesh, 

  ARR_DEP is either an A or a D, 

  CANCEL_CODE is either blank or a C

  FLIGHTD_ALL.OFFCHOCKS is 23/07/2012  16:10:00 (for example)

  Hi Sandston,

  The output of this formula must be same either from if or else condition.

  FLIGHTD_ALL.OFFCHOCKS is 23/07/2012  16:10:00 (for example)

  In your datetime field, convert into string.

  ToText({your_date_field})

  Also please specify return keyword.

  Please, Mark as Answer if this reply helped you.

  Hi Ajay, 

  I modified the code to:

  if {?ARR_DEP} = "A" then 
  {FLIGHTD_ALL.ACTUAL} 
  else 
  if {FLIGHTD_ALL.CANCEL_CODE} = "C" then 
  "" 
  else 
  ToText({FLIGHTD_ALL.OFFCHOCKS} )

  
  

  but advises a date-time is required here.

  I have managed to find a solution for the problem thanks to everyone that assisted with this:

  if {?ARR_DEP} = "D" and {FLIGHTD_ALL.CANCEL_CODE} <> "C" then 

  "" 

  else 

  if {?ARR_DEP} = "A" and {FLIGHTD_ALL.CANCEL_CODE} <> "" then 

  ToText({FLIGHTD_ALL.ACTUAL})

  else 

  ToText({FLIGHTD_ALL.OFFCHOCKS})
