PROCESSING MULTI-VALUED CHECKBOXES THROUGH WEBACTIONS

I could have sworn I'd seen something about the topic but absolutely
can't find it now. Need help quick, if possible.

I have a form with many checkboxes with the same name, different values.
If I use request-query-value to retrieve, I seem to just get the first
string. I can work-around with a multiple select I suppose, but I figure
I'm missing something -- probably something trivial.

So... Anyone know how to get the whole set of values from checkboxes
back into an action?

TIA
