[amibroker] Re: basic question about referencing bars

Trading Reference Links

i read the user guide thouroughly but it seems im missing something. 
i had tried "if(result == 1)" (with the equality operator) but it
gives me the same error as in the beginning:

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

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

it is still seeing "result" as an array instead of as a number!

"Condition in IF, WHILE, FOR statements has to be numeric or boolean
type. You cannot use an array here, please use [] (array subscript
operator) to access array elements"
