That's because that is not HTML code, but REBOL code. If you quote
it, as one big string, you don't have this problem.
print {Email Status}

Gabriele.

Ok, what you are seeing here is that PRINT will try to obtain the value of a
WORD! (datatype) within a block. the simple fix for the error you are seeing
is to enclose the words "Email Status" in quotes thus making it a STRING!
instead of a word. This should work...
#!rebol -cs
rebol [title: "EMail"]
print "content-type: text/html^/"
data: system/options/cgi/query-string
cgi: make object! decode-cgi data
print ["Email Status"]
failed: error? try [send to-email cgi/email cgi/message]
print either failed [
{the email could not be sent.}

[REBOL] Re: Problem with CGI
You got exactly what you were looking for. The molded value of system/options/cgi/query-string from a fresh console is "none" If you would like to know what the query string looks like try uploading a script to your server that looks something like: #!/path-to-rebol/rebol -cs print "Content-Type: text/html^/" ;-- Required Page Header print ["Probing query-string..."] probe system/options/cgi/query-string print [] A useful resource is www.rebol.org try searching for CGI and you will find many usefull examples and tools.

If I try to : mold system/options/cgi/query-string > then the system doesn't give to me the informations. > Why ? Because there's none to give. (When REBOL is first launched, as in your example below.) Query-strings are used on servers to catch the information added to the end of URLs, such as... http://www.google.com/search?q=rebol There, the "q=rebol" after the "?" is the query-string. If the Google website was using REBOL, "search" would be the script-name and each time it was run when someone did a search system/options/cgi/query-string would be loaded with what follows the "?". So, as far as I know, (I could be wrong - I'm no CGI expert), query-strings are only useful when REBOL is running on a server. If however you knew all that, are running REBOL on a server and still are having problems, then a fuller explanation of your problem is probably needed.
