Vlookup on 2 files - inserting vlookup command on another command

Hello, i am trying to print group name column(etc/group) on script (etc/passwd) since group name is not listed on etc/passwd columns. Im trying to do a vlookup. but i cant figure out how i can insert the vlookup command FNR==NR inside the print out command or the output. I also tried exporting etc/group and etc/passwd on a file but still cant find a way on how to do it.

Code:

awk -F":" -v TNR=$(wc -l < passwd.sh) '
BEGIN { NUM_PAGES=TNR/10+1
        print "--------------------------------------------------"
        printf "%-20s %-10s %-3s\n","USERNAME","GUID","DIRECTORY"
        print "--------------------------------------------------" }

!(NR%10) { PAGE++
           printf "--- Page %d of %d ---",PAGE,NUM_PAGES
           getline rc < "-"; system("tput cuu1") }

 #(NR==FNR) {a[$4];next}$3 in a{print $3}
 { printf "%-20s %-10s %-30s\n", $1,$3, $7 } ' group.sh  passwd.sh

groups

groups(1)						      General Commands Manual							 groups(1)

NAME

       groups - Displays your group membership

SYNOPSIS

       groups [user]

DESCRIPTION

       The  groups command writes to standard output the groups to which you or the specified user belong.  The Tru64 UNIX operating system allows
       a user to belong to many different groups at the same time.

       Your primary group is specified in the /etc/passwd file. Once you are logged in, you can change your active group  with	the  newgrp  shell
       command (see sh). When you create a file, its group ID is that of your active group.

       Other groups that you belong to are specified in the /etc/group file.  If you belong to more than one group, you can access files belonging
       to any of those groups without changing your primary group ID.  These are called your concurrent groups.

NOTES

       The /etc/passwd and /etc/group files must be on the same node.

EXAMPLES

       To determine your group membership, enter: groups

       The groups to which you belong will be displayed.  For example: devel  prod

FILES

       Contains group information.  Contains user information.
