awk help (external variable)

i need help with an awk question. i am looking to have an external variable be defined outside of awk but used in awk. so if we have fields $1, $2, $3 so on and so forth, i would like to be able to dictate what field is being printed by something like $[i]. so if i had a counter called test, make it 3 so the awk line would read `awk -F, '{ if ($[test] == "Annual") print $2}'. thus printing field 2 if field 3 equals Annual.

i hope i've somehow explained what i'm looking for. any thoughts, ideas, suggestions would be awesome. note that i am calling awk from within a function. call from case looks like this:

Code:

"02") get_jan_info "$(echo ${userpri[@]})" "$(echo ${usersec[@]})";;

code is here:

Code:

get_jan_info() {
        for pri_user in `awk -F, '{ if ($3 == "Annual") print $2;}' review.csv`
        do
               userpri[$num]=$pri_user  
               let "num = $num + 1"
        done

... #more that isn't relevant. 
}

thanks in advance.

IGAWK(1)							 Utility Commands							  IGAWK(1)

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
