# Assigning Values to Array

12

I have a simple formula that is calculating the FastK. I am using the ds array to allow me to access historical values as well. When I use the Print statement, it shows that it is calculating the formula properly, but it is not assigning the value to the specified array element. I have attached an image showing the output log. Anyone know why this would happen?

```class FastK
{
public:
// Variables
int Length;
double ds[];

// Constructors
FastK(void){};
FastK(int length)
{
Length=length;
ArraySetAsSeries(ds,true);
};

void Calculate(int shift)
{
int bar = Bars-IndicatorCounted();
if (bar<Length)
return;

double lowest = Low[iLowest(NULL,0,MODE_LOW,Length,shift)];
double highest = High[iHighest(NULL,0,MODE_HIGH,Length,shift)];
double num = Close[shift]-lowest;
double den = highest-lowest;

if (den!=0)
{
ds[shift]=num/den*100;
Print("ds = ",ds[shift],", formula = ",num/den*100);
}
else
ds[shift]=0;
};
};```

DS has no size. You can't assign to it until you resize it.

You are a gentleman and a scholar! I had a feeling I was overlooking the obvious. Thank you for your assistance.
