Shell script with awk command for counting in a file

Hi,
I hope you can help me with the awk command in shell scripting.
I want to do the following, but it doesn't work.
Code:
for i in $REF1 $REF2 $REF3; do
awk '{if($n>=0 && $n<=50000){count+=1}} END{print count}' ${DIR}${i} >${DIR}${i}_count.txt
done

REF1 to REF3 are only variables for .txt files.DIR is the working directory.
Is $n correct for the last column in the files? And I want to have an output file, where the variable count is print.
Can someone help me?

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
