Mandatory information about my setup:

Have I searched the tickets before posting? No
Have I searched the forum before posting? Yes
Have I read the documentation before posting (which pages?)? No
Joomla! version: 2.5.28
PHP version: 5.5.15
MySQL version: 5.6.20
Matukio version: 5.1.3
Direct link to the page that shows the issue: (local installation non public)


Description of my issue:
In frontend view I received
"Notice: Undefined offset: 3 in ..\htdocs\joomla\components\com_matukio\views\bookevent\tmpl\default.php on line 258"
It is located right below the standardform, before the additional fields starts.
The code line there on line 258 is: "switch ($zusart[3])"
Does the notice depends on a false input format that I was using trying to generate additional booking fields?

Thanks in advance
