I have no idea... but if you change your code to this, it works: $title_err = ($adTitle == "") ? 1 : (strlen($adTitle) > 50 ? 2 : 0); Does anyone know why ? René Yes... that's it. Your statement is probably evaluated like this:

$title_err = ( ($adTitle == "") ? 1 : strlen($adTitle) > 50 ) ? 2 : 0; The first ?: returns 1 so the second ?: will return 2 Regards René
