[Closed] makepreview multi cameras

Hello, I’m doing a script to mount a makepreview multi cameras,
but I’m building a script test to see how this code will be
behave, the more I’m not getting access to the fn populatelist
change the amount of frames:

try(destroyDialog theRollout)catch()

rollout theRollout “The Rollout” width:480 height:270
(
local pathR = “C:\”
local camRender = “”
local rW = (renderWidth )as string;
local rH = (renderHeight )as string;
global frStartv = animationRange.start
global frEndv = animationRange.end
local frameRend = “ccc”
local frameRstart = “ccc”

dotNetControl lv "system.windows.forms.listView" pos:[10,15] height:200 width:270

--Add columns.
fn populateList theLv=

	camera_array = for obj in cameras where iskindof obj camera collect obj

		append rows li		--Added the listViewItem to the rows array
	)
	theLv.items.addRange rows		--Add the array of rows to the listView control. 
)

fn initLv theLv=
(
	--Setup the forms view
	theLv.view=(dotNetClass "system.windows.forms.view").details
	theLv.Sorting = (dotNetClass "System.Windows.Forms.SortOrder").Ascending
	theLv.CheckBoxes = true

	theLv.GridLines=true			--Show lines between the items.
