OpenSSH config issue

I am way out of my element on this and hope someone can help.
Using Scott Klement's article (
http://systeminetwork.com/article/ssh-scp-and-sftp-tools-openssh) I am
trying to send files to a vendor using SFTP. I am forced, by the vendor,
to use the password authentication method. I have created my EXPECT file
and processed it through the following:

CALL QP2SHELL PARM('/usr/local/bin/expect' '-df' '/home/mkirkpat/
myexpectscript')

The EXPECT script is as follows (the PUT stmt has been removed):
#!/usr/local/bin/expect -f
spawn sftp WDS16000@xxxxxxxxxxxxxxxxxxxx
expect "Password:"
send "xxxx\n"
expect "sftp>"
send "quit\n"
exit

The following is displayed when executing the script(it looks like it may
be missing stty):

expect version 5.43.0
argv[0] = /usr/local/bin/expect argv[1] = -df argv[2] =
/home/mkirkpat/myexpectscript set argc 0
set argv0 "/home/mkirkpat/myexpectscript"
set argv ""
executing commands from command file /home/mkirkpat/myexpectscript
spawn sftp WDS16000@xxxxxxxxxxxxxxxxxxxx
