We have an internal joke at my place "it's always in the filters".
Just to double check - in your "promo ready" master smart list, are the filters set to qualify leads is ANY of those filters are true or ALL? Should be ANY.
yes! You are correct! I had not input double parenthesis around part of my filters logic,e.g.,:
1 and 2 and 3 and 4 and (5 and 6) or (6 and 7)
Should have been:
1 and 2 and 3 and 4 and ((5 and 6) or (6 and 7))
DOHHH!!! User error -again!
Thanks so much for your time in replying - I'd like to say that I figured this out by myself, but it was actually a Marketo Support rep - the marvelous, "David", who was kind enough to take a look at it while we were looking at a DNS issue.
