split 1D array into elements

In each iteration of a loop, I want to take root-mean-squre of the last 16520 elements of a 1D array (the last 10 seconds of sampled data). 

But I'm getting the following error: 

I also used "to double" converter, but I'm getting the 2nd error massage:

Use For Loop to Index ur FXP Array and use Convert it to DBL.  

X terminal of RMS Function is a Scalar DBL Element.

If u need work  just with some elements in array, use Array Subset function to index and put ur desired lenght.
