Need help with simple comparison in AWK

Hi,

I'm new to AWK and I'm having problems comparing a field to a string variable.

Code:
/ARTIST/ {x = $2}
$1 ~ x {print $0}

My code tries to find a record with the string "ARTIST". Once it finds it, it stores the second field of the record into a variable. I don't know what the problem is for the second line. The point is if the first field of a record matches the variable, it will print the entire record. But for some reason, it's not working.

Thanks, need help urgently!!

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
