Multiple Interval Function

[Alan2004]

Good Afternoon;

The following script is my first attempt to develop a subroutine which is called several times to calculate moving averages on different time periods. When the subroutine is called for one value, it works fine. When I add a second time period it does not perform correctly. I would appreciate suggestions on how to correct the coding to get the subroutine to function correctly.

Best Regards,

Alan
