Model counts limited to a roster scoped tag

[BGKenney]

Hello!

Working away on the new book for Warmachine. I'm trying to write a rule that is scoped to unit and limited to that unit's id. The model count for that unit needs to be limited to the number of warjacks in the roster +1.

I thought this would work, but it's not picking up the tagcount...any suggestions?

var jacks as number

jacks = (roster.tagcount[cmpgrp.warjack]) + 1
if (count[model] <= jacks) then
@valid = 1
endif

Thanks!
