Hi Troy,

Firstly, thanks for taking the time to answer. I've already doing all you said.

The only confusing part/difference to your solution above is in your example you've called your input parameter {/dataset/Invoices/WFID}....us there any reason you've used that {/dataset/Invoices/~) instead of just WFID? I've just called mine by a one-word identifier SREntryID without the whole variable syntax thing before it. Which confusingly is trying to tell me is a multivalued parameter (see image 2), when I haven't specified that anywhere.

As per image 3, when I try to call a Workflow Service Task and pass SREntryID to it (the last 'input' field in image 3), clicking the  > only allows me to select variables created from Form fields, which are further along in the flow. There is no SREntryID appearing there.
 

Hi Brett,

The default input parameter will automatically format to input parameter {/dataset/Invoices/<Variable Name>}. You can change the parameter name to whatever you want as shown below:

After making changes to the BP in cloud you must save and publish and then go to Workflow and sync the workflow with the BP as shown below:

Save,Publish and test.
