Alert page .. (Example)

[buuuudzik]

Hello,

I've tried to use the example from openrb.com:
http://openrb.com/alert-page-in-visualiz...ification/


But there is a problem somewhere here:

Code:

    if Page_Adding == true then
      -- Create alert page if alert page doesn't exist
      db:insert('visfloors', {building = alert_page_building, layout = alert_page_layout, sortorder = highest_sortorder, name = Alert_Page_Name, bgrepeat = 0, bgfixed = 0, adminonly = 0, width = alert_page_width, height = alert_page_height,})
    end
     
    -- Get page number of new created alert page
    alert_page_number = db:getone('SELECT id FROM visfloors WHERE name=?', Alert_Page_Name)

What is the problem?
