Hi Miruna, 

Retrieve Business Process Variables This workflow does not appear to be started by Forms. The Forms instance id was not specified or was empty.

Are you running this workflow from the Designer by pressing the play button? If so, that is expected behavior since it wouldn't have information on which Forms process instance to pull data from.

For testing purposes, you can click on the "advanced properties" button in the properties of the Retrieve Business Process Variable activity (the gear icon in the top right corner of the properties pane) and hardcode the IDs of the forms process and submission.  OR you need to run the full "pipeline" from the first submission in the Forms process so it calls into Workflow with the information needed.

Can you show be example of both the ID in the Process Instance and the pipeline??

On the Forms side, you can look at the process instance history under Monitoring and get the instance ID and the submission ID:

(the instance name is in the format <process name> <instance ID>: <submitter>)

On the Workflow side, you'd click on the Advanced Properties

And change the properties to use the values you got from Forms:

This way, you only have to submit the Forms once, then you can test the Workflow side until you're happy with the results.

Once you have everything tested, you will want to change the Retrieve Business Process Activity back to use the instance and submission that started workflow before you put this process in production so Forms can trigger this workflow and have it read the values from that instance instead of the hardcoded one.

Ok this look promising, I will try this, my next question is what you think of my workflow do you think this design will work??
