quantity of accessories/sizes follow-up question

["Edward Mack" <emack@mackcom.com>]

******    message to minivend-users from "Edward Mack" <emack@mackcom.com>     ******

I am interested in doing something that will show the quantity of sizes an
item is available in.  For example:  "This item is available in 4 sizes",
where the "4" would be generated based on the number of sizes (or commas) in
the sizes attribute field of the products database.  i.e.: 7", 8", 9", 10"

The following code was suggested and works, however it counts the number of
commas and spaces... So 7", 7 1/2", 8 1/2" gives me a result of 5 not the
desired result of 3.  I see the same behavior when using the
[loop-increment] tag.  Is there a way to choose the delimiter the [loop ...]
tag uses?

Thank you for your help!

[set sizeloopcount][/set]
   [loop arg=[item-field size]]
                                        [perl arg=scratch interpolate=1]
                                        $Safe{'scratch'}{'sizeloopcount'}
++;
                                        return '';
                                [/perl]
   [/loop]
There are [scratch sizeloopcount] sizes available.
