Parameter error or bill preview is blank for one File

If you receive a parameter error when billing a File in Amicus Billing this generally means the Send Bill option on the File is not checked.

To correct the setting:

1. Open the File being billed.
2. Access the Billing side of the File.
3. Select the Admin > General tab.
4. You will notice there is no check mark under the Send Bill column.
   
    
5. To correct the issue, check the Alternate Contact option. Select any Contact and move it to the right then click OK. Once done, remove the contact, by unchecking the Alternate Contact box. The check mark should now appear under the Send Bill column.
   
    
6. The Checkbox should now appear and be checked.
   
    
7. Delete any Draft Bills or Bills that couldn't be correctly accessed and re-run the Billing for those bills.
