Yes, that was going to be the next problem since some of the params I need to use are beyond position 15 which is all DNB is set to handle. I contacted the support team and they sent me a PHP script that accepts just the parameters you send it and takes care of the actual service call. (I suspect I'm not the first person who's had problems with their interface.)
So I think I can make this work by modifying their wrapper and using Response.Redirect to call it - just need to learn enough PHP to get it to post the results back to my WC method...

<sigh> who creates these methods with a billion parameters? Haven't these folks ever heard of using an object to hold values and passing a single value???
Most likely one of the values you're passing is not of the right type?
