You need quotes around the _expression_:

Hi all,
I need to create a raster file with the  if(fuel_class==4,3,if(fuel_class==8,15)) _expression_. I used the following command but it result a parse error.

r.mapcalc --overwrite _expression_=1hr_moisture = if(fuel_class==4,3,if(fuel_class==8,15))
r.mapcalc --overwrite _expression_="1hr_moisture = if(fuel_class==4,3,if(fuel_class==8,15))"

Also, what happens if feul_class is not 4 and not 8??

What could be the reason for the error?
