Will This Work ???

in the showFeeds.brs I created:

        item.cost = strtoi(item.cost)
        item.modelId = strtoi(item.modelId)
        
        m.cost = item.cost
        m.model = item.modelId

then on the appDetailScreen.brs I am trying to do the following: but does not seem to be quite right yet ? Any ideas?

 else if msg.isButtonPressed() 
                print "ButtonPressed"
                print "ButtonPressed"
                if msg.GetIndex() = 1
                
                    if m.cost = 25 then
                        funds = tokenValidation()
                            if funds = 1 then
                                exit while
                            else
                                chargeCustomer()
                            end if
                    end if                 
                        
                    PlayStart = RegRead(showList[showIndex].ContentId)
                    if PlayStart <> invalid then
                        showList[showIndex].PlayStart = PlayStart.ToInt()
                    endif

Function tokenValidation() As Integer  
  sn = GetDeviceESN()
  xfer = CreateObject("roURLTransfer")
  xfer.SetURL("http://allbabestv.com/mcams/roku/getCredits.php?deviceID=" + sn)
  response = xfer.GetToString()
  xml = CreateObject("roXMLElement")
  if xml.Parse(response)
    if (strtoi(xml.tokens) > item.cost)
      return 0
    end if
  end if
    return 1
end Function


Function chargeCustomer()
  sn = GetDeviceESN()
  xfer = CreateObject("roURLTransfer")
  xfer.SetURL("http://allbabestv.com/mcams/roku/chargeCustomer.php?deviceID=" + sn + "&cost=" + m.cost + "&model=" + m.model)
  response = xfer.GetToString()
end Function

Thanks for the help all
