I guess this is it Smilie WARNING: There is no error checking at all!

Code:
#!/bin/bash

ufile=$1 #user file name
ulf=$2 #user line from
ult=$3 #user line to

ifile=$4 #item file name
ilf=$5 #item line from
ilt=$6 #item line to

for user in `awk -vULF=$ulf -vULT=$ult 'NR>=ULF && NR<=ULT' $ufile` ; do
 for item in `awk -vILF=$ilf -vILT=$ilt 'NR>=ILF && NR<=ILT' $ifile` ; do
  echo $user @ $item
 done
done

Demonstration:
Code:
$ for i in {1..100}; do echo user$i >>userlist; done
$ for i in {1..100}; do echo item$i >>itemlist; done
$
$ ./script.sh userlist 23 30 itemlist 60 65

NAME
hobbitcgi.cfg - Command-line parameters for the Xymon CGI tools SYNOPSIS
$BBHOME/etc/hobbitcgi.cfg DESCRIPTION
hobbitcgi.cfg(1) controls the commandline options passed to all of the Xymon CGI tools through their respective shell-script wrappers. Typ- ically the options listed here are used for system-wide configuration of the CGI utilities, e.g. to define where they read configuration files. The exact set of commandline options available are described in the man-page for each of the CGI utilities. The file is "sourced" into the shell script wrapper, so assignments to the CGI-specific variables must follow standard shell-script syntax. SETTINGS

CGI_FINDHOST_OPTS Options for the bb-findhost.cgi(1) utility. CGI_HIST_OPTS Options for the bb-hist.cgi(1) utility. CGI_HOBBITCOLUMN_OPTS Xymon-specific options for column documentation. This uses the bb-csvinfo.cgi(1) utility with the server/etc/columndoc.cfg configu- ration file. CGI_HOBBITCONFREPORT_OPTS Options for the hobbit-confreport.cgi(1) utility. CGI_HOBBITGRAPH_OPTS Options for the hobbitgraph.cgi(1) utility. CGI_HOSTGRAPHS_OPTS Options for the hobbit-hostgraphs.cgi(1) utility. CGI_NKEDIT_OPTS Options for the hobbit-nkedit.cgi(1) utility.
