I have a custom variable set for all visitors; for our registered users it's some value, for unregistered users, it's empty.
I can find unregistered users in an advanced segment using the settings
Custom Variable (Value 02)
.+ -- works brilliantly.
But I need a report of unregistered visitors for a dashboard, and tried to do the same thing with a filter. I have a metric of Visits and a dimension of something all vistors will have (e.g. Browser). My filter is identical to the one in the advanced segment, but ... not brilliant. I get no visits. I have tried to
Include with a regex
^$ but no love there, either.
Any ideas what I am doing wrong?
