awk comparison with variable

hi,

I want to compare i variable in the awk statement but its not working out. Pl help me out

If we do the comparison like this its OK,

Code:
cat sample | awk -F" ", '{if ($1=="1-Sep-2009") print $1,$2,$3,$4,$5}'


But if u use a variable instead of "1-Sept-2009", it does not return anything,

Code:
d1=$(TZ=GMT-24 date +%cc | awk -F" ", '{print $1}')
d1=$(TZ=GMT-24 date +%cc | awk -F" ", '{print $2}')
cat sample | awk -F" ", '{if ($1==($d1"-"$d2"-2009") print $1,$2,$3,$4,$5}'


Pl suggest how can i incorporate this?

Thanks

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
