Hi Fritz,<div><br></div><div><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">John, indeed that was the problem.<br>
<br>
I wish that it would have been more obvious that this was the problem.<br>
<br>
There was a further problems with the code:<br>
1. number was not spelled correctly.<br>
2. the accessors for number need to be defined. I use the class re-factoring<br>
tool create the accessors.<br>
