Hi, I'm just starting to begin to make my own token but have run into a beginners problem
to the right of the solidity contract source code window there is an error message that reads 'Cannot compile source code'
The code I have input is exactly how it reads in the tutorial as follows...

contract MyToken {
/ This creates an array with all balances /
mapping (address => uint256) public balanceOf;

function MyToken(uint256 initialSupply) {
    balanceOf[msg.sender] = initialSupply;


Any help with what I may be doing wrong?

I have a good idea ... a good product but I need funding to develop what would be the best alternatives within the blokchain platform.

I look forward to helping you and your business.
