	ShowPlayerDialog(playerid,DIALOG_GROUPMEMBER,DIALOG_STYLE_MSGBOX,str2,str,"Close","");

	else SendClientMessage(playerid,-1,"Invalid Group name");
	return 1;
}

whats the problem?

Did you make sure it even reaches that part of code? Try putting a print just a line before ShowPlayerDialog, see if it prints anything.
