Ugh.... it's hideous!!! Your SQL is just plain wrong!!! Below is an example of a properly formatted query....

$result = mysql_query(SELECT * FROM * WHERE * = '*' ORDER BY *) or die(mysql_error());

Notice how firstly I have an or die statement at the end which basically says if there's an error tell me what and where (always good for development phase) and how my query is in CAPS!!

And as for the problem... I have no idea... but I just couldn't let the query format go.. its just so wrong!!

He didnt code it, so..yeah.

lol i did Invent, i recoded the entire thing thats why alot of things arn't eally working, i hadtocuz everyone flamed me if i didn't.. kkill change sql queries

Ugh.... it's hideous!!! Your SQL is just plain wrong!!! Below is an example of a properly formatted query....

$result = mysql_query(SELECT * FROM * WHERE * = '*' ORDER BY *) or die(mysql_error());

Both yours and his are correctly formatted, here's how I do mine:

$sql = mysql_query("SELECT `blah` FROM `noodles` WHERE `waffles` = 'bagels' AND `bagels` = 'nice' ORDER BY `sugar` DESC"); 

Notice how firstly I have an or die statement at the end which basically says if there's an error tell me what and where (always good for development phase) and how my query is in CAPS!!

Again, both yours and his queries are correct

And as for the problem... I have no idea... but I just couldn't let the query format go.. its just so wrong!!

The problem is this:
You aren't setting $start properly, you have this:

if(!isset($start))
        {
           $start=0;
        } 

Yet you never specify what to do when it's set
try this:

if(!isset($_GET["start"]) || !is_numerical($_GET["start"]))
{
    $start = "0";
}
else
{
    $start = $_GET["start"];
} 

That should do ya for.

Lolcoptrs good code +rep
I use a and or die statement test for errors then delete it all, but there were no sql errors, only wierd errors ;P
Also, im looking at some, css etc but i don't want to change every aspect is there any program that ill look through load of files and findand replac certain lines, because you can only go so far without changing html within the php

[Tomm]

Heres a SQL query to select records 10-20 for example..

SELECT * FROM table WHERE something='something' LIMIT 9,10

[Hypertext]

argh i thought is_numerical would make it work, it gave it a fatal error. as said apparently is_numerical isn't a defined function..?
