Dear Karim,
Thank you, now perhaps I can understand the problem. In B process I manage lists and only in a second phase strings. So I suppose that in managing lists the case sensitive has gone. Tomorrow I am out for examinations all day, as soon as possible I can to set again the process in B.
About spaces, yes, in this example there are no sound names wth spaces, but in the whole reservoire there are some, for example the names with the term “al ponticello”.
I think that by your suggestion I can afford the problem under another point of view, if I can not be able to resolve I will get in touch with you again. If I resolve I will put the solution in this diuscussion, if useful to someone other.
Meanwhile thank you very much.
Ciao
Fabio
