[mv] How to make Some items fractional & some not?

Ok so here's an interesting one.

We have a catalog that has FractionalItems Yes set and has a multiple item
order page.

Some items are fractional =1 in the database and some are fractional =0

How should/could/would we only allow items with fractional=1 to be ordered
fractionally?

We can order .5 pounds of something but not .5 of a can!

We tried variants on this;
<FORM ...
    <INPUT TYPE=hidden NAME=mv_check VALUE="Qty_Check">
    ...
    </FORM>


    [set Qty_Check]
    [perl]
    my $qty        = $CGI->{mv_orderitem_quantity};
    my $out = '';
    if ($qty =~ /\./i)  {
        $CGI->{mv_todo}     = 'return';
        $CGI->{mv_nextpage} = 'badqty';
    }
    return;
    [/perl]
    [/set]

but it didn't work and produces lots of code with each item. (25 on a
sheet).

Clues, Ideas, Samples welcome.

Regards,
Geoff
