How can I sum the limits-at of all child queues?

I’m “trying” to get a script that gets all the limit-at of the rules that match a parent and that in turn adds all the results in kilobits, so if for example I have 2 daughters with limit-at of 2M/2M I can get a final variable that results in $ example = 4000/4000 but I only get to the point where I get the limit-at I don’t know what else to do, I’ve already read the wiki and I can’t do anything else.
This is the script I have managed to do, but it only does half:

 :foreach b in=[/queue simple find parent=parent-example] d={
	:global test [/queue simple get $b limit-at];
	}

My native language is not English, so understanding the wiki is very difficult for me even with translators, however I understand most of the code I see, please, if you know how to do it, put it as an answer.

Greetings, because I do not think I have explained myself well in the other and in this I also detail that I have not been able to achieve it on my own. It is also written in another way in the hope that google translator does it well

Something like this would work.

#declare function
global parentTotal do={
#initialize total up and down vars
local totalUp 0
local totalDown 0
#loop over all childs
#print as-value generates an array of associative arrays for each entry
foreach item in=[/queue simple print as-value where parent=$1] do={
#get the limit-at value
local limitat ($item->"limit-at")
#split into up and down values
#up is from start up to /
#down is from /+1 char, to end of string
local up [pick $limitat 0 [find $limitat "/"]]
local down [pick $limitat ([find $limitat "/"]+1) [len $limitat]]
#add it up
set totalUp ($totalUp + $up)
set totalDown ($totalUp + $down)
}
#display and return result in up/down format
put ("$totalUp/$totalDown")
return ("$totalUp/$totalDown")
}

#usage
$parentTotal <parent name>

You still need to deal with “numbers” like 768k, 3M or 1G.

You have made me very happy! haha, but, in which part do I declare which is the parent to look for? Assuming your name is “parent_testtt”

I am using this:

 #declare function
global parentTotal do={
#initialize total up and down vars
local totalUp 0
local totalDown 0
#loop over all childs
#print as-value generates an array of associative arrays for each entry
foreach item in=[/queue simple print as-value where parent=$1] do={
#get the limit-at value
local limitat ($item->"limit-at")
#split into up and down values
#up is from start up to /
#down is from /+1 char, to end of string
local up [pick $limitat 0 [find $limitat "/"]]
local down [pick $limitat ([find $limitat "/"]+1) [len $limitat]]
#add it up
set totalUp ($totalUp + $up)
set totalDown ($totalUp + $down)
}
#display and return result in up/down format
put ("$totalUp/$totalDown")
return ("$totalUp/$totalDown")
}

#usage
$parentTotal <testparentname>

but it gives me 0/0 response
