Key error

[ellescuba27]

Please help right away! In PHP I am using MySQL and fetching the rows from a MySQL database. When I try to write this to the page, it writes "key error" and stops writing the rest of the page. Code where it seems to fail:

print "<tr><td style=\"background: url('crumpled".rand(1, 5).".jpg') repeat;\"><a name=\"$isdisplayarticlewritten[0]\"></a>";
$towrite .= "<h1>".str_replace("\n", "<br>", htmlentities($isdisplayarticlewritten[2]))."</h1>";

($isdisplayarticlewritten is the fetched row, $towrite is to be printed elsewhere on the page)

NVM, I got this one. I put in the wrong key. PHP was expecting a string, I set it to an interval. All fixed.
