Crystal Reports Suppress part of Address Field if the value is null

Hello,

I am working with Crystal Reports 11.  I am writing a formula to combine 3 address fields together.  However, one of the fields contains null values.  When it does contain a null value I want the extra space to go away.  

This is how the database looks:

Address1                     Address2               Address3
10 Main Street            Suite 5                    Boston, MA, 02118
20 Pleasant Street                                      Medford, MA, 02125

There is no Address 2 for the second line.

So my formula is this:

{Test.Address_1}+
ChrW(13)+
(If IsNull({Test.Address_2}) then
"" else {Test.Address_2})
+ChrW(13)
+ {Test.Address_3}

Result for Line 1:

10 Main Street
Suite 5
Boston, MA, 02118

Result for Line 2
20 Pleasant Street

Medford, MA, 02125

I want to remove the blank space between "20 Pleasant Street" and "Medford, MA, 02125" for the second result.

Thanks for any help,

Mike
