[Closed] Dialogbar UI not accessable

Hi there, I am working on a script that scans a folder for maxscripts and puts them all into a dropdownlist. The selected script can then be launched with pressing the run button.

This works perfect so far. But i wanted to put the dialog as a dockable dialogbar to stay permanent. I figured that out as well, but my problem is now that i cannot access the dropdownlist anymore.

Events like “on dropdownlist selected x do” dont work anymore.
How can i access the selected Value?

clearlistener()

try (cui.UnRegisterDialogBar Toolbar) catch()
if Toolbar != undefined do destroyDialog Toolbar

MyPath = @"\\Pathtoscripts\"

fn ScanforScripts =
(
	Scripts = getfiles (MyPath+"*.ms")
	for a=1 to Scripts.count do
	(
		Scripts[a] = getFilenameFile Scripts[a]
	)
	print scripts
)

ScanforScripts()

rollout Toolbar "Toolbar"
(
	dropdownlist Scriptlist items:Scripts width:120 pos:[4,4]
	Button Run "Run" pos:[128,4]
	Button Scan "Scan" pos:[168,4]
	
	on Scriptlist selected x do
	(
		print Scriptlist.selected
	)
	
	on Run pressed do
	(
		Filetorun = (MyPath+Toolbar.Scriptlist.selected+".ms")
		Filein Filetorun
	)
	
	on Scan pressed do
	(
		ScanforScripts()
		Scriptlist.items = Scripts
	)
)

createdialog Toolbar width:220 style:#(#style_toolwindow,#style_sysmenu)
cui.RegisterDialogBar Toolbar

If i disable the last line, everything works fine, but obviously it’s not a dialogbar anymore. Can someone help me out?
Apologies for my bad english…
