[ale] [OT] need help with 2php SOLUTION

[ChangingLINKS.com]

Yes. I have not been able to communicate it well because I am not a 
programmer. However, per your suggestion, I snippets from the actual code 
showing the problem and solution. Ironically, I was able to communicate all 
of this to a programmer who didn't speak english well.

<?
	//changebot lives!

	$with0s = "select * from table where code in( 'nu', '201' ) order by code 
limit 1";
	$res = mysql_query($with0s);
	if( mysql_num_rows( $res ) > 0 )
	{
//setting variables for the values in the columns
		$url = mysql_result($res,0,"url");
		$count = mysql_result($res,0,"count");
		$contacts =  mysql_result($res,0,"contacts");
		$linked = mysql_result($res,0,"linked");
		$id = mysql_result($res,0,"id");
//nodup function
		include ("noduplicate.php");
		deleteDuplicatedValues($url, $id);

/* CODE THAT DIDN'T WORK RIGHT
//this will show the value BEFORE the function was processed.
//this will not show the current value in column code.
		$code = mysql_result($res,0,"code");
		if($code != "newvaluesetbythefunction")
		echo "who\'s your daddy!"
*/

//HERE I run another query instead (CODE THAT DOES WORK)
  		$afternodup = "select code from links where id='$id'";
  		$nodupped = mysql_query($afternodup);
		$newcode = mysql_result($nodupped,0,"code");
		if( $newcode != "oldvalue" )
		{
		echo "It's ALL good!!!";
