This seems very easy to do, but I can't get it to work...

All I want to do is to have a Text box and a button... So I ask the user to write their E-mail in the text box and press the button... then I need that E-mail, and all the other e-mails saved in a text file on my site...

I've done this before but for some reason I can't get it work on a different host than what I have it on....

Thanks...
