Hi Krileon,
a warm thx for ur support to my desperate "case"

i know that my solution is a little complexe,

What you're trying to do however doesn't make a lot of sense and you may want to consider just redoing your fields configuration to better accommodate your needs.

so if you think of another way let me know, i am interested

Thank you.
So.

Hi krileon,
i do some tests and it may be a step .. but i first answer you,

I'd need to know why you're trying to extract the last value of a multiselect and what significance that last value has

it's about a field who assigne a sort of professionnel status, at the instant T All members display a single value ( of the same field) and it supposed to be the last they reached professionnaly (the last value).
why should I store all the values? it is to export a history of the different status obtained for each member.
and finally, why I did not create as many fields as status (values), it is because I already have many many other fields ..

and now for my step:
i add a line of code on component file (view.user)and now i can copy multiselect filed's values (all of them) in another field ... but not yet the last value
i am seeking for the 'syntax' i must add to my line , for getting the last value .
(for information, I am an ex-developer, but I have not developed for several years, I forgot the 'grammar' )

thx a lot,

So.

I will continue my tests to find the best and the simplest for me to get rid of this pb

by the way, can i ask you if u know about a plugin and/or a way to implement "back button" in the profile page ?
and to complexify a bit the navigation / back button should return the page-list-number we left just before
( ex. ex. I have 100 members on 4 pages of 25 lines, I am on page 3 and I open a profile page and the back button should bring me back to page 3 of my list) !?!

actually, i added a back button on profiles's pages, but it always bring me back to the first page of my list
thank you
