Why is my ERC20 token transferring from 0x000000 when Im explicitly giving an address to transfer from?

Question

When calling transferFrom it uses address 0x00000 instead of the address I am passing to it.

I have insured the token is minted when constructed and total supply is sent to contract owner's wallet address. Right before calling transferFrom ownerAddress and contractAddress are both defined but it still seems to ignore the from address.

Token contract {   

address public ownerAddress;
uint256 public initialSupply = 100000000000;

constructor(string memory _name, string memory _symbol, uint8 _decimals) 
ERC20Detailed(_name, _symbol, _decimals)
public {
    ownerAddress = msg.sender;
    _mint(msg.sender, initialSupply);
} 



function createTokenSale(uint256 rate,uint256 cap) public verifyOwner() returns(address) {

    TokenSale newTokenSale = new TokenSale(rate, msg.sender, this, cap );
    address tokenSaleAddress = address(newTokenSale);

    emit LogSaleAndOwnerAddress(tokenSaleAddress, ownerAddress); // both addresses are as expected here

    this.transferFrom(ownerAddress, tokenSaleAddress, initialSupply); //this attempts to transfer from 0x0000 to tokenSaleAddress  ??????

    return tokenSaleAddress;
}
}

I expect "from" address to be ownerAddress but instead its 0x00000

ownerAddress is undefined. Did you mean owner?

yes sorry that was a mistake. I meant ownerAddress. So when it logs LogSaleAndOwnerAddress it knows what ownerAddress is. – Richard Ryan Garcia Jul 23 '19 at 01:24
