Variable or Field 'nameOfVariable' declared void no idea why :(

I've googled and searched on various websites and I can not work out why I get the follow errors from one of my functions.

error: variable or field 'ConnectClient' declared void

error: 'Socket' was not declared in this scope

Both of those errors are for the line 38 of my code, which is the...

void ConnectClient(Socket _newConnection)

From what I understood from other posts asking about this question, it normally came down to inconsistencies with the header file (Which I'm NOT using for this little test) or they had a return type in the void function which I don't have.

NOTE: I've removed extra bits of code that relate to part of the game code, and stacks of commented out code which I was testing. This program is a little test into winsock use

{
    for (int slotIndex = 0; slotIndex < serverMaxClients; slotIndex++)
    {

        {
            return slotIndex;
        }
    }
    return -1;

Two problems here.

1)It should be SOCKET, not Socket.

2) You're missing a semi-colon (;) at end of the cout statement above.

Fix those two errors above, the related compiler errors in main() and your code will at least compile. As to whether it works or not...
