Sure thing ...

They're getting passed ... don't worry, you're just not reading them,

Consult your sysadmin for that informaton - simple test is to make a
simple helloworld.php and a helloworld.php3 file and upload with:

<?php echo "hello world"; ?>

And see what you get in each case.

Now, on to your code:
> form.php
>        <select name="Type_of_Event[]" size="3" multiple>
<many snips>
> 
> print "Type_of_Event:<br>\n";

I'm not sure about that foreach syntax. I would use a for loop like so:

for($i=0;$i<count($Type_of_Event);++$i){
	print $Type_of_Event[$i];
	print "\n";
};

Hope that helps -- I made a test page - but only internally -- check the
code at the end of this note and save as foo.php
