I am building a drupal site for my business and have a question regarding the Selective Better Exposed Filters module. I have been messing around with Drupal for a few years but I still have so much to learn.

I have 2 exposed filters on a view that will display required services that will need to be completed to a vehicle. The content type that will be displayed on the page will be the required services and contains 2 fields that use taxonomy (vehicle make & service qualifiers). Vehicle make is limited to a single value per content node while service qualifiers can have multiple values all pulled from the taxonomy vocabularies. 

I am trying to use the Selective Better Exposed Filters module to limit the values in the 2nd exposed filter to only the service qualifier taxonomy terms that would apply to the vehicle make that was chosen in the first exposed filter but all values for all vehicle makes show and it doesn't change. The vehicle make filter does not appear to have an affect the second filter whatsoever. I have checked the boxes for both "Show only used items" & "Filter items based on filtered result set" in the Better Exposed Filters settings under both filters. I am using the content fields instead of the "Has Taxonomy Term" for filter criteria as I had read it would not work using that filter.

Am I missing something else here needed to make this work? Any help is greatly appreciated!

Thanks!
