ISPConfig 3.0.5 RC1 & web2ftp-install.sh on Debian Squeeze

I am having problems getting this script to work. I tried it and noticed that the line numbers to insert/modify in the script were wrong for ISPConfig 3.0.5 RC1. I think that I adjusted them properly but I still can't get it to work.
Does this have to be done before the install of ISPConfig 3?

I added the webftp url "/webftp" in System > Interface > Main Config > Sites > WebFTP URL, but still nothing.

Code:

# cat web2ftp.sh 
#!/bin/bash
set -x

# Download, unzip, and more
cd /tmp
wget http://www.net2ftp.com/download/net2ftp_v0.98.zip
unzip net2ftp_v0.98.zip
cd net2ftp_v0.98
mv files_to_upload /var/www/webftp
cd ..
/bin/rm -R net2ftp_v0.98
