Good man!
Three final things:
1) Your link to output.php should not be at the end of your form. It should only show after submit where it says 'Thank you username'
After this line in form.php:
echo "Thank you $username !";paste
echo "<a href='www.yoursite.com'>somelink</a>";Do not use double quotations in the <a> tag.
2) At a later stage try editing the code I suggested earlier. As it stands users are allowed to enter non-numeric values into your amount text box.
3) When your happy with everything don't forget to close this thread (mark as solved at bottom of page).
Glad to help, later!
