You are still using the multipart node AND there is none of the flow that I did for you.

Then use the flow I prepared for you.  
Replace the inject node with whatever supplies the data.  
Just check that the format going into the HTTP Request is as specified in the help (and in my demo flow)

> this new url is needed to give another http request

So use the dashboard form values in the URL field of the HTTP Request...
