[GRASS-user] Error while applying r.mapcalc to an output from GROW

[António Rocha]

Hi
THanks Markus
I sent an email directly to you instead of the mailing list. And I made 
a mistake in the previous email.
Here goes:

But I still have one question.
In this case I want to transform all pixels that are not 
myscript.tmpvalid at National ==1 and myscript.tmpcloud at National !=1 to 
NULL and the rest to the values that exists in raster B1. So I built 
this function in r.mapcalc

if(( myscript.tmpvalid at National ==1 && myscript.tmpcloud at National 
!=1),B.1,null())

The thing is:
I gett all NULLS
And If I do:
If I do if(( myscript.tmpvalid at National ==1 && 
myscript.tmpcloud at National !=1),B.1,1000)
I get 1000 where I don't meet those conditions and, nulls where I 
suppose to have my B.1. values. B.1 ranges from 0.03 til 0.67
WHat am I doing wrong?
