You should be able to do this, I believe, though I'm not positive.  In 
any case, when you have stacked values like this on a particular 
variable, the values are munged into a single long value with a null 
character as the delimiter.

If you want to treat this as an array of values, you can potentially get 
at it with the [value-extended] tag.

I haven't used this tag much and it isn't necessarily clear from the 
docs whether it's working on CGI-space values or Values-space values...

Anyway, I hope this helps you.
