Accordion: removeClass('selected')

Accordion: removeClass('selected')

I am using the Accordion menu to filter a data table.  The menu contains two filters, with multiple options under each.  You can only have ONE filter selected at a time.  If you click between the two options under the first filter, the style class, 'selected' is added and removed without a problem.  If you click an option under the second filter though, it DOESN'T remove the 'selected' class from the first filter.  Any help would be appreciated.  Thank you.
