But below you say using the enter key should work, that was the problem,
it doesn't work.

I think it was pretty damned simple.

Who knows? Mysterious things happen. I didn't know what the problem was.

Obviously this is a snippet and there is a <table> structure above this
snippet.

No, that was the problem, it doesn't pass:
if (isset($_REQUEST["buy"]))
when using the enter key, only when clicking the button.
I should have included the if clause in my OP.

What FAQ?

_without_ another field with the same name in the same form, since it
sounds like your form handler is simplistic and could get confused with
that.


Yes, this was the problem.
