I don't understand what you are saying, you accept that
@expert_pagination is a number, but then expect to be able to say
@expert_pagination.current.  A number does not have a method current
so the error is shown.  What do you expect @expert_pagination.current
to do if @expert_pagination is a simple number?

I also don't understand what you mean by "when the number is like 6,7"
 6,7 is not a number, or do you mean 6.7?

Have you followed my earlier suggestion to read the Rails Guide on
debugging in order to find out what is going on?  Please answer this
question if you reply, do not just ignore it.
