moving average, issue with types

[Paski]

Hi,
I'm planning on adding a moving average function to average an analog input and trigger some actions if that decreases too much.
for that, i'm declaring an array of the tension in the config.g

global TensionAverage = {0,0,0,0,0,0} ;list of 6 tension to average the tension in a moving average

And in a macro called by deamon.g is the following. with parameter P being the analog senor reading

;Tension WatchDog

;tension average: list of 1 elements, move element i to i+1. scrap element 5. add current to element 0
var i = 5
var average = 0
while var.i>0
    set global.TensionAverage[var.i] = global.TensionAverage[var.i-1]
    set var.average = var.average + global.TensionAverage[var.i]
    set var.i = var.i -1
set global.TensionAverage[0]=param.P
set var.average = var.average + global.TensionAverage[0]

set var.average = var.average /6
echo "average: "^{var.average}

if var.average < global.TensTreshold*0.5
    m98 P"/sys/tension-error.g"

But in line 7, i got this error:
"error: in file macro line 7 column 70: meta command: Cannot index into variable or parameter 'TensionAverage^' of non-array type"

so, my question is, is there a more efficient way to get the moving average with Gcode/metacomands?
how can i cast it to an array?
Thanks!

@Paski firmware version?

@dc42 RRF 3,5.4

@Paski can you try firmware 3.6.0-rc.2 ? I think this may have been fixed already.

@dc42 Will try. Thanks David
