Multiple Parameter Values In Variable

[subevenis]

I'm trying to use multiple values for a parameter within a variable, and would like to know firstly if this is possible, and secondly how to do it.

I have variable v.Example (obviously I am using proxies as I can't show my details)

Sum({< Category1 = {"$1"},
              Category2 = {"$2"}>}
Amount)/1000))

Category1 can take the following values up, down, left, right

Category2 can take the following values peppermint, topspin, Cthulu - 

So if I'm looking for say Category1 to be down, and Category2 to be Cthulu, I would now write

$(v.Example(down, Cthulu))

I would like to be able to select more than one value for each parameter, so I would like to use something similar to the below.

$(v.Example(down, [peppermint, Cthulu]))

Can someone please help out with the correct syntax? 

Cheers

It's possible but you need to avoid any commas within the parameter because they will be always treated as delimiter for the parameter itself. In your case you may write it in this way:

$(v.Example((down|left), (peppermint|Cthulu)))
