Suppressing blank lines in an address block

Okay, I've been fooling around with this about an hour. It's time to bring in the experts!

I'm using CR 2008.

I'm trying to suppress blank lines in an address block on a form I'm creating (customer statements). I'm a professional programmer just starting to fool around with CR.

Bad:
===============================
Acme Hardware
123 Easy Lane
(blank)
New York, NY  12345
===============================

Good:
===============================
Acme Hardware
123 Easy Lane
New York, NY  12345
===============================

I've tried to solve this using a formula. I've set it to "Basic Syntax". (See attached)

The formula is returning blanks.

What am I doing wrong?

Thanks for your help.

dim buf as String

buf = {COMPANIES.COMPANY_NAME}

if Length({COMPANIES.ADDRESS1}) > 0 then 
  buf = buf & Chr(13) & {COMPANIES.ADDRESS1}
end if

if Length({COMPANIES.ADDRESS2}) > 0 then 
  buf = buf & Chr(13) & {COMPANIES.ADDRESS2}
end if

if Length({COMPANIES.ADDRESS3}) > 0 then 
  buf = buf & Chr(13) & {COMPANIES.ADDRESS3}
end if

if Length({COMPANIES.CITY}) > 0 then 
  buf = buf & Chr(13) & {COMPANIES.CITY} & ", " & {COMPANIES.CITY} & "  " & {COMPANIES.ZIP_CODE}
end if

if (Length({COMPANIES.COUNTRY}) > 0) and ({COMPANIES.COUNTRY} <> "US") then 
  buf = buf & Chr(13) & {COMPANIES.COUNTRY}
end if


formula = buf

Found the answer:

There's an option at the top of the Formula editor dialog that deals with Nulls. I needed to set the choice to "Default Value For Nulls". The default setting was "Exception for Nulls".

What was happening was the blank fields were, in fact, null and the "Exception" was being triggered which caused the formula to return a blank.

Rule #1, know your data.

Perhaps you need Length(Trim({COMPANIES.ADDRESS3})) > 0

I don't see anything wrong with the formula so long as the fields are empty or NULL if they don't have a value.

Since that isn't the formula you are using since it has CITY in twice and missing State.

Can you copy and paste the actual formula?
