Hello Expert,

Hope Somebody help me with this topic! So I'm new to odoo and I'm trying to use compute Fields

Here is the situation i have transactions and agents where every transaction has a specific agent

My question is:

I want to put a field on Agents that calculate automatically the number of transaction of the related agent

I know i can use Computed Field so i put field on agents and name it "Total Transactions" and go to odoo studio and trying to put in the compute field the rule without any chance

can somebody guide me how can i do this or maybe give me an example similar to this situation

Thanks
