Awk shell variables inside make

[Domingo A. Siliceo]

Hello.

I'm using GNU Make 3.81 under xUbuntu 8.04

I have the following lines inside a Makefile (simplified here)

----------8<--------------------8<---------------------
all: placas.html discos.html
#       cd /home/dsiliceo/Trabajo/Site_build
        mv -v placas.html ../Site/placas.html
        mv -v discos.html ../Site/discos.html

#
# proceso de placas
#
placas.html: placas placas_1.html placas_2.html pie.html

# Concatenamos las tres partes del fichero
        cat placas_1.html placas_2.html pie.html > placas.html
        
placas_2.html:
# generamos el contenido de la tabla
	awk -F";" '{if ($11 == 1)  {print \ 
"<tr><td><small>$2</small><td><small>$4</small><td><small>$3</small><td><small><a\ 
href="$8">p&aacute;gina del fabricante</a></small><td\ 
align=right><small>$10&euro;</small>"} }; END {print "</table><p>"}'\ 
placas >> placas_2.html

[...Makefile follows...]
------------8<---------------8<----------------------

The problem I'm having is that the awk command doesn't interprets the 
shell variables, thus I'm obtaining a placas_2.html only with the HTML 
tags. Should I write these shell variables diferently?

I hope I explained myself clear.

Thanks.
