Превод - Swedish-Английски - * Du kan inte anmäla intresse pÃ¥ fler objekt....

I changed "objekts" to "objects".

depending on context "... interest in more than one object" could sound better in English

But is that what the original says? That's a bit different, I think.

No, "... more than one object" doesn't match here.

It just says that the person is not allowed to select more objects, and doesn't mention how many objects this person has already selected.

Thanks, casper. I've validated the translation.
