As Konstantinos said, it's because the dialog title has an array. Instead, I'd suggest you use something like:

pawn Код:

ShowPlayerDialog(playerid, dregister1, DIALOG_STYLE_MSGBOX, "Chromosome", "What type of chromosome combination are you XX, or XY?", "XX", "XY");

And then for the OnDialogResponse, for the XY combination, it could be defined as if(!response) and for the XX combination it could be defined as if(response).. just an idea instead of the list style. That's what I'm using for my Male / Female selection on my server.
