    <p>I am having a problem with my Google App Engine Program. I have been staring at it for a few hours now, and don't what the solution is. I have seen another relevant question <a href="https://stackoverflow.com/questions/10012476/badvalueerror-property-category-is-required-on-gae">&quot;BadValueError: Property category is required&quot; on GAE</a>, but even when I remove the "required=True" condition from both the user and USD variables, I receive the same error.</p> <p>My program does a simple conversion of USD currency to SR currency.

    1. COThis looks like it should be a syntax error, but can you try `float(self.request.get('currency'))` instead of `((float)self.request.get('currency')))`?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
