$query="UPDATE CATS set CATTITLE=\"$CATTITLE\" where CATNUM=\"$CATNUM\"";

$test=mysql_db_query("db22667a",$query);

this suppose that you pass CATNUM by posting $CATNUM and the new value of CATTITLE in $CATTITLE

It's time to clean up this topic area and that means taking care of this question. Your options at this point are:

1. Award points to the Expert who provided an answer, or who helped you most. Do this by clicking on the "Accept Comment as Answer" button that lies above and to the right of the appropriate expert's name.

2. PAQ the question because the information might be useful to others, but was not useful to you. To use this option, you must state why the question is no longer useful to you, and the experts need to let me know if they feel that you're being unfair.

3.  Ask Community Support to help split points between participating experts.  Just comment here with details.

4.  Delete the question because it is of no value to you or to anyone else.  To use this option, you must state why the question is no longer useful to you, and the experts need to let me know if they feel that you're being unfair.

If you elect for option 2, 3 or 4, just post comment with details here and I'll take it from there.  We also request that you review any other open questions you might have and update/close them.  Display all your question history from your Member Profile to view details.

PLEASE DO NOT AWARD THE POINTS TO ME.
