So i'm making a function that will return index of current combo box item but can't realize it in code
function:

Code:

function messageComboBox( name, items)
local form = createForm(false)
form.Width = 220
form.Height = 140
form.BorderStyle = bsSingle
form.Position = poScreenCenter
form.PopupMode = 0
form.Caption = name

local combobox = createComboBox(form)
combobox.Width = 200
combobox.AnchorSideLeft.Control = form
combobox.AnchorSideTop.Control = form
combobox.BorderSpacing.Left = 10
combobox.BorderSpacing.Top = 5

local button = createButton(form)
button.Width = 50
button.AnchorSideLeft.Control = form
button.AnchorSideTop.Control = form
button.BorderSpacing.Left = form.Width / 2
button.BorderSpacing.Top = 120
button.Caption = 'OK'

for i = 0,#items do
combobox.items.add(tostring(items[i]))
end

form.OnClose = function(sender)
return caFree
end

form.Show()

end
