Contextual Filters with multiple arguments Why isn't this view filtering correctly? I have four contextual filters applied to one view:

The view is filtering a list of projects by four properties, Region, Client, Type, and State.  When the view-page is loaded, all 4 arguments will be supplied.  The problem I'm having is:

The first two arguments, Region and State, filter correctly.  The last two: Type and State do not affect the filter.

The Type field isn't being factored into the query at all. You can see content with both Roadway and Airport values for the type field show up, but none for Asian or Military which are correctly filtered out values for the first two arguments (Region and Client).

I have tried remaking the filters, re-arranging the filters to make type first, re-entering some of the test content to make sure it wasn't corrupted.. no luck yet.
Okay- I figured out what was going on.  I'm going to answer my own question in case anyone runs into the same problem I had.

Previously I had specified some PHP Validation code to the Type and State filters.  Thinking they might be causing the problem I turned off the validation for both of them, but the problem persisted and that's why I posted my question above.  To solve this you need to overwrite the previous validation you set by setting it to something like Basic validation, thus clearing out the old code.  Now it works like it should but it seems like there is a bug in Views though that doesn't properly unset validation code.  Good luck!
