I am using Rinkeby in Ethereum Wallet and have created a crowdsale contract which created ERC20 tokens, assigned the crowdsale as the owner and then sold them to addresses which bought them using the buyToken function I coded into the crowdsale.
Now the accounts which purchased the tokens possess them and can transfer them to accounts via the "Transfer Ether and Tokens" button in Ethereum Wallet. But I don't know how to access any of the other functions (the ERC20 functions: totalSupply, balanceOf, allowance, approve, transferFrom).
I was able to do this for tokens where I just deployed the contract of the token by itself directly, but now using a crowdsale contract which creates the token contract and is assigned as the owner of the wallet, I don't know how token holders can access these functions in Ethereum wallet.
I appreciate any help in this. Thank you.
