Setting Assignment Rules

Setting Assignment Rules

Hey

I fetching my leads from wordpress contact form-7 to ZOHO CRM through lead magnet plugin. I am able to get the leads in my module. 
Now I want to assign these leads to the respective team members. For that I used Assignment rules and created the same.
But whenever the lead comes it is not assigned.
Could anyone help me out with this issue?

Thanks
