HIde SSRS report navigation toolbar in CRM 2011 using hidden field

Hi,

I am creating HTML web resource to display SSRS report within entity form.  I want to hide the toolbar.  form.action = context.getServerUrl()+'/CRMReports/rsviewer/reportviewer.aspx';

I used <input type="hidden" name="PromptAreaCollapsed" value="true" /> to hide Parameter Prompt.  How do I use the similar hidden field to hide the navigation tool bar?  Thanks.
