Retrieve Salesforce records to assist with payment approval process

Hi, 

I'm very new here so apologies if this has been answered somewhere else already but I couldn't find anything while searching. 

I'm trying to create a payment approval form so our dealer network can request and receive approval to work quickly and easily. 

To do this, I've created a form that asked the dealer for the case number of the job they're working on. What I want to then do is retrieve the details of that case from Salesforce, including other relevant customer information, to then pass to the approving managers for approval. the Salesforce info will mean the managers do not have to manually look up all the info they need to make their decision as it will all be present for them in the approval request email they receive. 

That's the concept anyway. 

So far I've created the form and have been able to successfully query salesforce with the job number and get a result (I think, it says it worked but I can't see a record or anything to confirm).

What do I do next? How do i actually retrieve the case details once I've successfully queried salesforce?

I've tried taking the output of the query records and using it as an input for a salesforce "retrieve a record" action but I get an error in that step. Not sure what I'm doing wrong here. Any help would be appreciated. 

Kind Regards,
