passing sysint variable to API

I am trying to pass some variables into an api using delphi 6.

function  Login(const Server: WideString; Port: sysint;
                    const Username: WideString; const Password: WideString): WideString

procedure TForm1.Button1Click(Sender: TObject);
islogin : widestring;
 server := 'testserver';
 username := 'user1';
 password := 'password';
 port := 11977;
islogin := globo.Login(servername,portnumber,username,password);

I get an access violation - am I not passing the correct variable for a sysint / can you provide examples of a sysint variable?;

you have two differently named variables:

port := 11977;

Sorry - That line should read:

islogin := globo.Login(servername,port,username,password);

Is a sysint variable like an integer?
yes.  it's basically an INT.

============ you have ?
   uses activex;

Thanks for posting again,

I have activex under my uses clause....., perhaps the access violation is nothing to do with the parameters I am passing to it.
how about the 'server' versus 'servername' difference?

how are your variables declared?
