Hello!
I'm studing Ethereum and its smart contracts now. It's about tokens and crowdsale.
I have deployed via Etherium Wallet 0.9.2 two example smart-contracts (from here:
https://ethereum.org/token#the-code and here:
https://ethereum.org/crowdsale#the-code) in private network succesfully (mining is on).
But if i try to send Ether from main address to crowdsale-contract address i see this error: "It seems this transaction will fail. If you submit it, it may consume all the gas you provide."
Also in transaction confirmation window i see this message: "Estimated fee consumption: The contract won't allow this transaction to be executed".
If I ignore this messages and make confirmation, than window closes and nothing happens. Balance is same as before and no tokens received.
Could You help me with the answer what i do wrong?
Thanks a lot!
