contenu(y)
----------------------
Here the error:
88:in 'contenu': undefined method 'text' for nil:NilClass
(NoMethodError)from 95:in '<main>'
----------------------
My question: why the price-line(prix) work differently of the two others
before her?
She works fine if i put a number, and don't work with the "nb" whithout
.to_i.
This may be a link with the character € (it's for that the -2 at line
90, because it show "?" instead).
If you are french, i am too, et mon anglais n'est pas assez avancé pour
tout comprendre en cette langue.
looks like 'css("span")[4]' is returning nil
insert a line before line 88:
inspect @page.css("tr")[nb.to_i].css("span")
to see if the data matches what you expect

it should print the object
from your code you should see an array of at least 4 items, since you are
trying to grab the fourth
If it is printing a list of less then 4 items, or is nil, thats the cause
of the error
the job then is to figure out why your input is not as you expect
