Filtering an HTML view by Country and State without making hundreds of pages with iframes?

Filtering an HTML view by Country and State without making hundreds of pages with iframes?

I have a form that collects country and state service area information from groups via 2 multiselect fields.  They are multiselect because groups can provide services to one or more states or even countries.  This information will be accessible to the public to find groups nearest to them. 

I need a way to display the data once the user selects the criteria.  They will select their region, then their country, then if in the US or Canada, their state/province.  This will take them to an HTML view that will pull the data from the table based on the country and/or state they select, which is the crux of my question.

I already have the user interface for selecting region/country/state created on the existing website, so that isn't the issue.  The issue is, with an HTML view (most likely to be embedded in an iframe), will I have to make a separate page with an iframe for each country and state/province?  Or is there a way to use just one page and pass the parameters to it somehow?

I already know I can add filtering parameters to my iframe code.  But this would require me to make hundreds of pages on my website to house each iframe.  If this is the only way, I'm willing to do it, but I'm all about finding an easier way.  I'm pretty sure I can't pass anything through a URL to an HTML view the way I can with a default Zoho view.

I have another post asking a different question on this, but that explains more of what I need to do, at http://help.zoho.com/portal/en/community/topic/displaying-complete-records-not-just-a-few-fields-from-2-forms-in-1-view-possible.

Thanks for your help.
