[Zope-DB] zpt -> retaining the value of a radio button selected

[Laura McCord]

I have a form that when a radio button is selected it updates the
database but the radio button unchecks once the page reloads. Is there a
way to keep whatever selection is checked?

I don't know if this involves a query to see what value is in the field
and based on that value the form needs to check that radio button.

Any suggestions would be great.

Thanks.
