cannot find symbol constructor

im having problems with the compiling of the program im doing, i get
this error message: cannot find symbol constructor SignUp() on this
statment...this is just a part of the whole program by the way...

Code:

public void actionPerformed(ActionEvent e)
{
if(e.getActionCommand().equals("Add User")){
!!!HERE!!! SignUp sign = new SignUp();//calls the signup dialog
}
else if(e.getActionCommand().equals("Delete User")){
try{
statement = connection.createStatement();
query = ("DELETE FROM registration where rusername = '"
/*+(String)userlist.getSelectedValue()+"'"*/);
statement.executeUpdate(query);
statement.close();
}
catch(Exception err){
err.printStackTrace();
System.out.print(err.toString());
}

}
else if(e.getActionCommand().equals("Log out")){
System.exit(0);
}
}

i dont get it since all im trying to do is open the
SignUp(SignUp.java) dialog box which is also located in the same
folder whenever id press the Add User button(its a button)...what
could be the problem? help please....
