[amibroker] Re: basic question about referencing bars

thanks for bearing with me. ok i'm making some progress but still got
new setbacks.

variableX = variableY / abs(variableZ);
result = IIf (variableX > .5, 1, 0);

if(result = 1){
Filter = Open > 40 & Open < 60;
}

the problem now is that "result" is evaluating to true (1) even when
"variableX" is in reality less < .5

therefore i'm getting all tickers in the 40-60 Open range. I only want
to get the tickers where "variableX" is more > .5

does it make sense?
