Help with mktime() parameter warning

[streetrodfanati]

Hello, I need a bit of help- I get the following error on my site when I add a banner:

Warning: mktime() expects parameter 3 to be long, string given in /home/goldenpl/public_html/ptc/admin2/banners.php on line 69

Here is the file code:

<?
$includes[title]="Banner Manager";


if($action == "add") {
		$sql=$Db1->query("INSERT INTO banners SET 
		title='".htmlentities($title)."',
		target='$target',
		banner='$banner',
		username='$user',
		credits='$credits'");
		$Db1->sql_close();
		header("Location: index.php?view=admin&ac=banners&".$url_variables."");
}

if(($step == "") && ($search == 1)) {
	header("Location: index.php?view=admin&ac=banners&search=1&search_str=$search_str&search_by=$search_by&step=2&orderby=$orderby&type=$type");
	exit;
}

if($search == 1) {
	$search_str2=explode(" ", $search_str);
	for($x=0; $x<count($search_str2); $x++) {
		$conditions.=" banners.$search_by LIKE '%$search_str2[$x]%' ";
		if($x < (count($search_str2)-1)) {
			$conditions .= " AND ";
		}
	}

Any help would be greatly appreciated!

$this_banner[dsub] is probably returning a string instead of an integer. If you're sure it is an integer you can try:

(int)$this_banner[dsub]

otherwise, check it's contents.

That did the trick! Thank you!
