 :o((   my result  = Test and Out  blanck, nothing, nada !!??


[seti tva][data table="tva" column="taux" key="[item-field Cat_tva]"][/seti]
[seti subtotalvar][item-subtotal noformat=1][/seti]

[perl interpolate=1 arg='scratch values']
          my a$;
          my b$;
          $Safe{'scratch'}->{'var1'} = $Safe{'scratch'}->{'tva'};
          $Safe{'scratch'}->{'var2'} = $Safe{'scratch'}->{'subtotalvar'};
          $a = $Safe{'scratch'}->{'var1'};
          $b = ($Safe{'scratch'}->{'var2'} * $Safe{'scratch'}->{'var1'});
          $Safe{'scratch'}->{'test'} = $a;
          $Safe{'scratch'}->{'out'} = $b;
          return '';
[/perl]

tva : 0.196                     ([scratch tva])
subtotalvar : 2500        ([scratch subtotalvar])
test :                             ([scratch test])
out :                              ([scratch out])
