[TYPO3-project-seminars] How to change errormessage that is displayed when required checkbox is unchecked?

[Leif Albrecht]

Hi community,

I would like to know how I can change the text that is diyplayed -during
registration process- when the customer left a required checkbox unchecked.
Now it says ' Please accept the terms for travelling in order to register
for this event. /Bitte akzeptieren Sie die Reisebedingungen, um sich für
diese Veranstaltung anzumelden.'. The label besides the checkbox could
easily be changed via Typoscript
(plugin.tx_seminars_pi1._LOCAL_LANG.de.label_terms_2 = Ich habe die
Teilnahmebedingungen gelesen und akzeptiert.) but this doesn´t seem to work
for the error message belonging to this checkbox. Even changing it directly
in /pi1/locallang.xml doesn´t have any effects.

Thanks for your help!
Leif Albrecht
