Code errors due to misspelled variable

In cubilis_fastbooker_widget.php in function getCubilisLongLang the parameter is $shortLocale but in the code you use $shorLocale (missing t):

private function getCubilisLongLang($shortLocale)
	{
		//nl-NL, fr-FR, en-GB, de-DE
		$longLocale = strtr (get_locale(), array ('_' => '-'));
		if ($shortLocale !== null && !empty($shortLocale)) {
			if ($shortLocale == 'nl') {
				$longLocale = "nl-NL";
			} elseif ($shortLocale == 'fr') {
				$longLocale = "fr-FR";
			} elseif (<strong>$shorLocale</strong>  == 'en') {
				$longLocale = "en-GB";
			} elseif (<strong>$shorLocale</strong>  == 'de') {
				$longLocale = "de-DE";
			} else {
				$longLocale = "en-GB";
			}
		}

		return $longLocale;
	}

Could you please correct the code and release a new version.
Thanks.
