Hi Darrel,
Here is the entire code on that link:

' This routine will keep a "Running Average" of 10-bit Analog Values 
' Instead of adding a bunch of values together and then dividing by the number 
' of samples, it averages each sample into the final result immediately.
' This eliminates the need for 32 bit math.
' To allow it to "Catch up" to large changes, set the FAspread to an 
' acceptable range.
' Simply place the new number in VALUE and GoSub Average 
' The Average (with Hysterisis) will be returned into the same variable VALUE

It may not have been put in there properly. Can you click the link and see what you get?

From the code, it jumps over the section staring with:
' -=-=-=-=-=-= Average Analog values -=-=-=-=-=-=-=-=-=-=

It does not seem to make sense to me.

Thanks. :-)
