SOAP Request - maybe HTTP Request - To Navision 2018 Soap webservice

Hello,

Trying to emulate what you have done to make yours work!

Here is the soap I am trying to access:

http://www.aaacooper.com/ws/ActDocumentSearch.asmx?wsdl

It works using the following XML

I have set up my HTTP request activity as follows, but i think i am missing something with the header. What do you think?

The body is the full XML string

This is what I have for headers

Lastly, this is what is being outputted.

Where am I going wrong!?
Thanks
