Hello,


 I meet a big problem at the level of the basket, of a boutique (file
voir.js)
The customers can not command more than 20 articles different .
The 21-th article erases the 1-st.
Could you indicate to me lines concerned JavaScript ?
(I am not very good in Javascript .....)
How make possible order with  one  unlimited number of articles ?
Thank you in advance.

 Warmly,
Juliette  from France.
