Parameter error or bill preview is blank for one file

From time to time you may receive a parameter error when billing.

This generally means that the Send Bill option on the file is not checked

To resolve:

Open the file(s) being billed

Access the Billing side of the file.

Select the Admin tab.

You will notice under the column Send Bill there is no check mark.

To fix this, access the Alternate Contact option on the bottom left.

Select this option and choose any other contact to the right and click OK. Once that is done, remove this contact, by unchecking the box beside Alternate Contact. You will then notice a check mark under the Send Bill column.

Delete and re-run the draft bill
