paginated report filter by sellers

Hi !

I'm new to this and face some difficulties with the paginated report builder.

I created my different tables thanks to their DAX queries exported from PBI which traduce activities of my sellers. They each have a column with the "seller_name", and I'd like to create a report which present my tables but filtered for each sellers one after another so I can send it to them personnaly. 

Is it possible ? I created a parameter but it seems not to filter right the tables...

Can someone please help me 😞 ? 

Thank you !
