Please follow the rules as posted on daniweb otherwise in future you may have to suffer the consequences such as point deduction or banning. So please keep your code tidy by placing it in the appropriate code tags and it isn't nice when long sentences are purely in caps. So try not to break any more rules in future.

Our Web Development forum category encompasses everything related to building a website from the ground up. Topics include serverside scripting, clientside scripting, databases, and web / graphic design. When posting programming code, encase it in [ code], [ code=syntax], or [ icode] bbcode tags. Please only link to your website if it is necessary to demonstrate how something isn't working.
Our PHP forum is the place for Q&A-style discussions related to this popular development language. LAMP programmers will appreciate our separate Apache forum, within the Networking sub-category of the Hardware and Software category, and MySQL forum, also within the Web Development category.

As per the question you have asked it is in the following syntax that you need to correct:

$result = mysql_query($sql) or die(mysql_error());

Notice the "or die(mysql_error());" after the mysql_query() function. This will reviel the true error which is a sql syntax error for your mysql query input ($sql). By fixing the $sql variable or the string you manually inputed you will solve the entire problem. So do "or die(mysql_error());" after each mysql_query()" and tell us the new error.
