 # Exercise 7 - User Tasks and Task Output Parameters
 
-This exercise introduces a new scenario which will serve as an example where [User Tasks](../learning/concepts/bpmn/user-task.md), resource download and [Task Output Parameters](../learning/concepts/fhir/task.md#task-output-parameters)
+This exercise introduces a new scenario which will serve as an example where [User Tasks](../learning/concepts/bpmn/user-tasks.md), resource download and [Task Output Parameters](../learning/concepts/fhir/task.md#task-output-parameters)
 will be utilized. The scenario is a voting process where one DSF instances of the tutorial setup will send a binary question (yes/no) to the other instances and itself.
 The question can be set when starting the voting process. The question can will then be answerable through a [QuestionnaireResponse](https://www.hl7.org/fhir/R4/questionnaireresponse.html) resource on the instance's DSF FHIR server.
 The answer then gets sent back to the instance which initiated the voting process.
 The scenario comes with a skeleton including two BPMN models. One for orchestrating the voting process called found in `voting-process.bpmn` and the subprocess which handles the vote itself found in `vote.bpmn`. 
-It also includes most of the Java implementation for both processes and the required FHIR resources. Your task will be to fill in the parts concerning the [User Task](../learning/concepts/bpmn/user-task.md)

    If referenced, the DSF will take this [Questionnaire](https://www.hl7.org/fhir/R4/questionnaire.html) as a template to create the [QuestionnaireResponse](https://www.hl7.org/fhir/R4/questionnaireresponse.html)
    that can be answered by a user in the DSF FHIR server web UI.

      The connection from the [Exclusive Gateway](../learning/concepts/bpmn/gateways.md) requires a [Condition](../learning/concepts/bpmn/conditions.md) element with type `Expression` and `Condition Expression` with value `${userVote}`.
    * The [Questionnaire](https://www.hl7.org/fhir/R4/questionnaire.html) resource is referenced by providing a `Form key` attribute with the value of the [Questionnaire](https://www.hl7.org/fhir/R4/questionnaire.html) URL you created in the previous step appended by the version placeholder `|#{version}`. This option is found under `Forms` and type `Embedded or External Task Forms`.
 4. The [QuestionnaireResponse](https://www.hl7.org/fhir/R4/questionnaireresponse.html) that is automatically created will copy its items from the template [Questionnaire](https://www.hl7.org/fhir/R4/questionnaire.html).
    This means we need a way to set the `item.text` element of the `binary-question` item you created in the previous step, dynamically. This mechanism is provided by [Task Listeners](https://docs.camunda.org/manual/7.21/user-guide/process-engine/delegation-code/#task-listener).
