Labelling highways

[Steve Pashby]

Hello, 

I'm trying to label some roads with a highway sign and then overlay their 
respective number.  However, for some reason i either label the entire road 
with highway signs or just get the highway number ! 

I guess it has something to do with defining a 'highway sign' SYMBOL and then 
using that in the LAYER definition ?

... Any help will be greatly appreciated !

Cheers, 
Steve.
