How to delete all Helpers with no Children?

weird! now is working! )))
thanks once again

Thank you! Unfortunately, I couldn't make it work. When I run the script, nothing happens. I made some edits by removing the portion 'and (h.children).count == 0' because in this case, all helpers are moving to HLP layers, not just the empty ones.
Appreciate your efforts!

I would also appreciate help with the MaxScript command to move all Helper objects to the 'HLP' layer. Thank you!

For the Point helpers only:

(
	hlpLayer = layerManager.getLayerFromName "HLP"
	if hlpLayer == undefined do hlpLayer = layerManager.newLayerFromName "HLP"
	for h in helpers where (classof h == Point) and (h.children).count == 0 do hlpLayer.addNode h	
)

For all helpers:

(
	hlpLayer = layerManager.getLayerFromName "HLP"
	if hlpLayer == undefined do hlpLayer = layerManager.newLayerFromName "HLP"
	for h in helpers where (h.children).count == 0 do hlpLayer.addNode h	
)

works like a charm - thank you!

unfortunately nothing is happens with the Helper object once I run script

delete (for h in helpers where (classof h == Point) and (h.children).count == 0 collect h)

try this

delete (for h in helpers where (classof h == Point) and (h.children == undefined) collect h)
