Error "Bill to Company is required"

[lscoast]

I am getting the error:

Reason: Bill To Company is required.
isError: 1

What does that mean?  I thought company was optional.  I am using AIM.

It optional unless your account setting set the field as required.

For test account https://test.authorize.net/ or for production account https://secure.authorize.net/
