You didn't show your cfc function, but your syntax in your cfinput is 100%
correct. You can pass additional values to a cfc via Autosuggest exactly as
you've shown.

If CompanyNumber was already assigned a value on your form page, you only need
to set it up as an argument in your cfc.

What autosuggest can't do is mimic the best use of the old HTML select/option
tag, where you would display CompanyNames in the drop down but use
CompanyNumber as the submit value. Autosuggest can be populated with a
one-dimensional array only.
