my tunnel

I am trying to get something similar established. The following code is ~/bin/mytunnel.sh
Code:
#!/bin/sh
# ~/bin/my_tunnel.sh
tunnel_up=`ps ax|grep 1080 | grep -v 'grep'`
if [ "${tunnel_up}" = "" ]; then
ssh -D 127.0.0.1:1080 andyhase@tripleyou.dyndns.org & &0 < 'password'
fi

I would like to have the script insert the password via stdin when the password question of ssh comes up. As of right now I get the error message:
Code:
 5: Syntax error: "&" unexpected

Thanks, Andreas

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
