How to make the result of a fold statement a constant?

[SmartCoder]

Hi,

I have the following code in a fold statement:

def recentGreenBack = fold x = 1 to 21 with green = 0 while green == 0 do if indicator[x] == 1 then x else 0;

This generates the right number as I have tested it on the chart. Now, I am trying to run the following code:

def cond1 = indicator[recentGreenBack ] == 1;

I am getting the error that I can only put constants in this expression " indicator[recentGreenBack ] " Could someone please explain how I can convert the recentGreenBack to a constant?

Thanks

Use 'GetValue'.
Should be something like this:

def cond1 = GetValue(indicator, recentGreenBack) == 1;
