hello, one another idea :
For easy translate userfields / customfield
in formjob.php
change this line :
<label id=' . $userfield->name . 'msg for="' . $userfield->name . '" >' . $userfield->title . '</label> <font color="red">*</font>
by
<label id=' . $userfield->name . 'msg for="' . $userfield->name . '" >' . JText::_($userfield->title) . '</label> <font color="red">*</font>
if the title of your customfield / userfields is not in your language file : is the title (default value) that is displayed.
if the title of your customfield / userfields is inserted your language file : is translation that is displayed.
exemple for customfield with title : YOU ARE THE BEST
add this line on your language file (french example) : YOU ARE THE BEST="VOUS ÊTES LE MEILLEUR"
And joomla translate your customfield
