Sending multiple attachments from a form

If anybody could take a look at this form to see where I'm going wrong, I'd really appreciate it. I'm stumped and can't figure out where the problem is:

	{

	// get the sender's name and email address
	// we'll just plug them a variable to be used later

	// generate a random string to be used as the boundary marker
	$mime_boundary="==Multipart_Boundary_x".md5(mt_rand())."x";

	// here we'll hard code a text messge

The problem that is happening is that the script attaches the first file to the email but not the second.

If you look at the outout of file2 though you see that everything is setup correctly. I think there may be something incorrect with the boundary but I'm not sure what.

Well, I finally got it working (no thanks to anybody 😛). I think the code below would be a good place for people to start.

If anybody has any questions, feel free to drop me a line.
