541688 Update Joomla component

We have a Joomla website using Community Builder and the Eventlist component. In the CB profile, we have information about 1, 2 or 3 boats for each user. Eventlist is used to register events for boats. On this site, we have a small own written component that makes it possible for one specific Joomla user (“evenementen”) to update a table where we link a boat to an event in Eventlist. We want you to make a small change to this component: each Joomla user (when logged in) should be able to link his own boat(s) to an event. Changes by an user are only allowed till x days before the start of an event. If this number of days is reached, user should get a message “x days before an event it is no longer possible to change, please click here to contact the event coordinator”. We should be able to change the number of days (x) and the text of this message. User “Evenementen” should still be able to assign all boats, also within the x days. We do have a test site available.
