Shell Programming and Scripting

Hello,
I am trying to write an expect script that will ssh into a large number of Cisco routers and add some commands via the cli. The script I wrote works great for one host however I have over 350 routers that this needs to be added to. The problem is I cannot get the script to read the file of hosts. Below is the shell script and the expect script. The host file is called host_list. Any suggestions would be very much appreciated as I am about to pull my hair out. Thanks.

[~]$ cat pan_hosts
#!/usr/local/bin/bash
cat ./host_list | while read hosts; do
./pan $LINE
done

--------

[~]$ cat pan
#!/usr/local/bin/expect
set host [lindex $argv 0]
spawn ssh -l root $host
set timeout 7
expect "assword: $"
send "xxxxxxxxx\n"
expect "#"
send "config t\n"
expect "onfig)#"
send "ntp server 10.10.1.89 prefer\n"
expect "onfig)#"
send "ntp source vlan 1\n"
expect "onfig)#"
send "clock timezone CST -6\n"
expect "onfig)#"
send "clock summer-time CDT recurring\n"
expect "onfig)#"
send "access-list 88 permit 65.242.29.0 0.0.0.255\n"
expect "onfig)#"
send "access-list 88 permit 24.182.133.64 0.0.0.7\n"
expect "onfig)#"
send "snmp-server community xxxxxxxxxxxxxxxxxx rw 88\n"
expect "onfig)#"
send "exit\n"
expect "#"
send "wr\n"
expect "#"
send "exit\n"

I was able to figure out what the issue was even with my 2nd grade expect education.
