Could not set Name via Business Process and Business Rule

Hi,



I have a small problem,

I have a custom section "Client" and I created a custom field UsrName.

When lead is created, I auto create Client by setting lead.contact_name as client.usrname but it always got set as null/empty string.

In the same business process, I am creating a contact using lead.contact_name as contact.fullname and it works perfectly.



I tried setting a business rule as well that when lead is filled in, it auto copies the lead.contact_name as client.usrname, but it didn't work.



Do you have any idea why this doesn't work?







Best Regards,

Solem A.
