Hi everyone,
I’m new to the forum.
I’m trying to evaluate whether tryton is suitable for our company. I have installed Tryton 7.0 on an Ubuntu virtual server and have added some modules that I think I need. Including the German chart of accounts skr04. The server is running and can be accessed on the LAN via both the client and the browser. So far so good.
After I have made the basic settings for our company and the accounting, I am in the process of setting up the payment conditions.
I created a rule “30 days net” and set the Remainder to 30 days.
When I run “Test Payment Term” I get the following error message:
```auto
Traceback (most recent call last):

id = int(id)
ValueError: invalid literal for int() with base 10: 'add'
Fault: invalid literal for int() with base 10: 'add'
```
I’m not a programmer, so someone can give me a hint what is going wrong?
Thx,
Christian

This is a known bug that was fixed: [Test payment term wizard crashes (#12775) · Issues · Tryton / Tryton · GitLab](https://bugs.tryton.org/issue12775)
But it seems I forgot to backport it in 7.0 series.

Hi Cedric,
thanks for the quick reply.
Does that mean that the rule works, but the test doesn’t? Have I understood that correctly?

I do not know if your rule works but the test does not without the fix.
