and the productItems collection looks like this:

I have a mapping for my create order service (which writes to the order collection as follows:

I am getting an error because I am passing a string for the userid instead of the user collection. Can you advise how to do this?

Hello Terry,

In a column of type pointer you should pass not the line but json.
Please add in mapping to request parameter CustomerId this js code

codereturn {"collName":"_users", "explained":value};/code

var id = localStorage.getItem("userid");
return {"collName" : "users", "id" : id};

worked a treat, Thanks
