[minimcmonkey 0]

Hi.
Im new to perl and CGI
could someone tell me how to run CGI on Xisto free hosting.
I have created a programme which look like

print "<p>Hi</p>";

i tried saving it in notepad as "test.cgi"
but it saved as a text document, named "test.cgi"
I tried putting it in the "cgi-bin" area, on the free web hosting ftp.
but when i ran it, it said it couldnt find it.

could someone help me.

Also, how do you use the first line like:

#! usr/bin/perl
