            The following script code sets the area parameter of 'Q6' to values of 100, 200 and 400 for the
        first, second and third steps respectively.
            
Let values = [1, 2, 4]
Let step = GetCurrentStepValue()
Let value = values[step-1]
Let SetInstanceParamValue('q6', 'area', value)
