Pass through a list into a sql statement with parameter

I have a list from an existing query called "RiskDataSetID" which contains numerical values (i.e. 741,738,736....n). I created a parameter for this list and i am trying to implement it into the where statement of my sql query to try and limit the data i am pulling. I am running into an error which states "We cannot apply operator & to types Text and Number."

Here is the query i am trying to update using the parameter

select *

from db..databaseresults

where riskdatasetid in (RiskDataSetID parameter)
