How to create Butler board button with cards assigned to multiple members

[Jeff Cohan]

I want to have a Butler board button that creates and emails a report showing information about all cards (with the green "To Do" label) that are assigned to EITHER @member1 or @member2. My attempts appear to treat the "assigned to" clauses as conjunctive (gotta be BOTH), as the reports are empty. I realize I could create two different reports, but I don't want to. Below are snippets from 2 of my attempts.

create a report
with all cards with the green "To Do" label
assigned to member @member1
assigned to member @member2
using pattern "[{cardname}]({cardlink})\n\nAssigned to: *{cardmemberfullnames}*\n\nLabel(s): *{labelnames}*\n\n--\n\n",
and send an email notification to "me@somewhere.com"
with subject "Todos Report" and message "{$report}"

create a report
with all cards with the green "To Do" label
assigned to member @member1
with the green "To Do" label
assigned to member @member2
using pattern "[{cardname}]({cardlink})\n\nAssigned to: *{cardmemberfullnames}*\n\nLabel(s): *{labelnames}*\n\n--\n\n",
and send an email notification to "me@somewhere.com"
with subject "Todos Report" and message "{$report}"

Your help would be appreciated.
