pass username, pwd, server information in expect shell scripting

I want to pass all the remote server names as shell script arguments and then want my script to copy the given file/directory to all remote servers. Below is my code.

#!/bin/bash
/usr/bin/expect <<EOD

#connect via scp

usr=Joe
pwd=Password
file_location=/home/file1.txt

for a in $@
do
  spawn scp -r $file_location  "$usr@$a:$file_location"

expect -nocase "password: "

send "$pwd\r"

expect eof
EOD

Username and password is same for all the remote servers. So I am hard-coding them for time being but while running the script I see a problem with that..

>./scp1.sh server1 server2
invalid command name "usr=Joe"
while executing
"usr=Joe"

Any help is appreciated. Thanks!

To read command line arguments from expect:

$argc - number items of arguments passed to a script.
$argv - list of the arguments.
$argv0 - name of the script.

This was take from this site

If you want more help with expect then google about tcl because expect is an extension to tcl language
