Dataset in Perspective Reporting Module

Hello !
I am trying to pass a dataset in parameter to a report in order to display it in a table.

My issue is that the dataset columns never appear in the parameters of the report, so I am not able to display them. (I want to display only 3 of the 6 column of the dataset)
Could someone help me on this please ?
