After some tests :

give an error ( "Symbol's value as variable is void:
org-babel-current-src-block-location")

==> After some tests, it works in changing the "setq" part as
 val1 (or val1 (string-to-number
            (org-entry-get org-babel-current-src-block-location "VAL1" t)
                ))

I can't figure out why...

==> I will try with python...

Thanks
