As far as the error goes, did you look it up in the Users Guide where it is explained?
To count true and false results, one way to go is to define trueresult and falseresult and put them into individual columns, e.g., filter = 1; trueresult = ... falseresult = ... addcolumn(trueresult, ... addcolumn(falseresult, ... You can also incorporate cum(), sum(), lastvalue() with trueresult and falseresult to produce what you want.
