The meaning of this error is, your query string is not giving a valid result set after executing the query using mysql_query().

Before pass the query to mysql_query() function, just print it back to the web page and then manually execute the generated query string in the query analyser. Then you can find out the, errors in the sql statement (If any and I guess)
Thanks.

hi,
not sure if this is the reason as i don't know your database structure

in your first example you are using
[PHP]SELECT * FROM articles where id={$_REQUEST['id']};[/PHP]

i'm assuming that the id is an interger.

whereas in the second example you are using

[PHP]select * from cards where card={$_REQUEST['card']}[/PHP]

is the $_REQUEST['card'] meant to be a string or an interger.

if string then you need apostrophes around the $_REQUEST['card']
