Where exactly do you need help?

What is not working, and how is it failing?

Also, you should not interpolate user-supplied data into strings and then pass them to your SQL database. Use DBI placeholders instead.

Also, this code looks suspicious:

    while( ($ARTICLE{'name'},$ARTICLE{'author'},$ARTICLE{'label'},$ART
+ICLE{'price'},$ARTICLE{'pochette'},$ARTICLE{'genre'})=$c->fetchrow())
+ {
        $total +=1;
    }

Maybe you wanted to do a select count(*) from ... instead, to make the database do the work?
