Token Example Error

[ccconnor]

Hello,
I'm trying to learn smart contract according to https://www.ethereum.org/token. I'm using remix IDE, and the enviroment option is JavaScript VM. The contract is deployed succefully, but when I try to buy tokens, remix shows errors "the constructor should be payable if you send value". After I added payable keyword, the buy function still failed. The code I'm using is just the same as the above url shows, or https://gist.github.com/6d78ad3e351cb8799339d99a9c3def51.
Can someone offer any suggestions?

By the way, when value is less than sellPrice, "buy" succeeded， when eual or large, failed.

buyPrice is by default 0, this is why the tx fails, try calling setPrices before

First thanks for you reply. But I've already set price.

@heyconnor Have you got it worked?

[ccconnor]

@Aniket-Engg Finally I didn't use buy and sell interface.

[Aniket-Engg]

Okay. Your gist is broken. Are you still looking to get it worked?

[ccconnor]

@Aniket-Engg That gist was the same as official site's. I used a simple one.
