--lua
local function returnhandle (value)
      var = {}
      for i = 1, #value do
            table.insert (var,value[i][1][1]) -- value what i need, it contains process id
      end
      return var
end

arr = {findwindow ('name1'), findwindow ('name2')} -- windows to search with individual names
group = returnhandle (arr)

log (table.concat(group, " "))

how to avoid to get error "attempt to index nil value", i mean more what check i need to do, to not try table.insert nil value, i get such error if window name is typed incorrect and value is nil

if value[i] ~= nil then
    table.insert (var, value[i][1][1]) -- value what i need, it contains process id
end
