Testing with &

[paul.timm]

I'm an art guy so please pardon me if this is a really obvious thing.

I'm working on stats and need to run a text to find all Character cards with a Cost Type of E and average the number in the associate cost group.

<stat id="charavge" name="Avg E cost Char" scope="deck1" visibility="always">
<test> type.Char? & CostType.E </test>
<calc> avg:cost.? </calc>
</stat>

I keep running into an "unrecognized special token" error based on the &, but I can't see any other way to do it.
