The web service requires to input an associated array (ie. username, password) - it seems to me that Delphi does NOT support associated array, therefore I have defined a class for it in Delphi - however, I got the following error - on Incompatible type

[Error] loginclient.pas(70): E2010 Incompatible types: 'loginserver.UserDetail' and 'loginclient.UserDetail'
[Fatal Error] login.dpr(6): F2063 Could not compile used unit 'loginclient.pas'
Please kindly advice. Thank you in advance.
