how do i pattern match a field with awk?

hi,

let's say $numbers = "324 350 587" an so on...
what i'm trying to do is this:

awk -v numbers="$numbers" '{if (numbers ~ /$2/) print $0, "bla bla"}' file

# file looks like this:
214 .....
215 ...
216 ....
250
...
324
325
...
350 something ...
...
587 ...

i want to do something with the lines that contain the numbers in the variable numbers, and something else with the lines that match other patterns.

thanks..

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
