Ok
So im making a little uploader in html on dreamweaver.
So i have the "choose file" tab where you click it and you choose which file you want to upload.
Then i have a "upload" tab, but i carnt figure out how to make it make you go to a page where it shows your file and links to it?
+Rep will be awarded to people who give advice that works.

Thanks very much!

I might have made some errors, and I'm not sure if it's 100% secure, so use it at your own risk..
