Can you fill me in on the difference between AddWithValue and just Adding a parameter? I assumed they were the same except one included setting the value. Maybe I was wrong and probably is the case considering the issue.

For the Output parameters you need to provide all details (type and length). This is only possible with Add method, not a quickie AddWithValue.

Also, you should try avoiding AddWithValue in the actual code. It's much better to always be 100% explicit and therefore use Add method. AddWithValue is only used because its syntax is simpler and easier to remember.
