Attached is a revised version of the "XAverage" function called 
"XAverage.V" that will accept variables as the price series input.

It is a "simple" function so must be called on every bar to get the 
same values as the XAverage function. This means you should not use 
it inside some conditional statement.

INCORRECT usage:

    if <condition> then begin
       Value3 = XAverage.V(Value2, 30);  {Only called on some bars}
    end

CORRECT usage:

    Value1 = XAverage.V(Value2, 30);       {Called on every bar}

    if <condition> then begin
       Value3 = Value1;
    end

(The input "Length" should be a fixed value (constant or variable) 
that does not change from bar to bar since it is only used in the 
function on CurrentBar = 1.)
