The formula below works but I would like to omit lines that are blank.

i.e.
=CONCATENATE(I15,CHAR(10),J15,CHAR(10),K15,CHAR(10 ),L15,CHAR(10),M15,CHAR(10),N15,CHAR(10),O15)

Say line K15, L15 and M15 had no data like this :

I 227 Finney Lane
J Heald Green
K
L
M
N Cheadle
O SK8 3QB

How can I tell it to omit the blank lines, K,L,M so the address is without
blanks?

Your help would be much appreciated.

Thanx
