# Check Parametric Cardinal Placements

You can check that a cardinal placement has occurred correctly by comparing the response from QMS with the result that IDOL Server returns when you send the same query directly to it.

You can also use the request log for the Promotion Agentstore to check that a rule returned. Send the `GRL` action to the Promotion Agentstore. You can click the query in the log to run it, and see if a parametric cardinal placement rule returns.
