I'm trying to split my ETH/ETC from a presale wallet in Mist v0.8.10. I've followed the original Steemit post on running the split contract yet when I go to run the contract it doesn't show a field to input the number of coins I wish to split. I would obviously like to send a small amount first to ensure if all works as desired. Any ideas on what I'm missing?
In Ethereum Wallet, on the contract interface page, there is a drop-down list under Write To Contract. Select the Split function, enter the two addresses that you wan to split to, then select the sender address under Execute From and input the amount that you want to split in the box under Send Ether. You can click the word Ether to select Finney, which will let you input the ammount to send in units of 1/1000 ETH.
It appears that for some reason this functionality is only available in the Ethereum Wallet application, and not in the full Mist browser. Please install Ethereum Wallet from here: https://github.com/ethereum/mist/releases
