trying to deploy crowdsale on Test-net
follow the step on https://www.ethereum.org/crowdsale#how-to-use
use an account to transfer ether to the [Crowdsale]
but jsut no value on balanceOf of [Crowdsale] , and balanceOf of [MyToken]
seems nothing works ^^"
can help me to debug....
source code on : https://www.asuswebstorage.com/navigate/s/48C849848BB245F18905C8F499C65DD6Y


PS:
there is a warning , when transfer ether to the [Crowdsale] , like this :Issue won't allow this transaction (Smart contract) , but i had add more and more gas to do ether transfer...not works..


--update 20170512--
find one solution, to Fixed [MyToken] , then the buy record / token was successfully created in [Crowdsale] and [MyToken] .
please reference : Unable to contribute to crowdsale contract
just need to add variable "owner" , to replace "msg.sender" and operate [MyToken] constructor() / transfer().... that's works!!
