Hi,

I am currently trying to install the module Billing, with no success so =
far.
The first problem I encounterd was that Costreg module also was needed =
(it needed some MySql tables from it to modify). This one was easy to =
overcome.

The second problem was that either the old (pushd to the attic) module =
Finance is needed or a class from the Billing module is corrupt or =
broken.

the error displayd:

 Fatal error: Call to a member function on a non-object in =
/usr/local/www/data-dist/default/atk/relations/class.atkmanytoonerelation=
.inc on line 207=20

Going through the Mailing lists I found that this error can be generated =
due to a missing value in one of the classes of a module
  userelation("atkmanytoonerelation");
at the top of the classes where it was missing.

This did not resolve the problem.

Can anybody out there assist me or point me in the right direction?

The Achievo version I am using is : Achievo 1.1 (latest stable build)
Modules I am using are all the stable modules.


With kind regards,

P. Tierlier
