So here's a section of of a class i have to write a test class for. They want 90% coverage, I'm at 87%, lol woe is me. 

My one problem is the wrapper class, through the rest of the code and this snippet it's the one thing i can't seem to get coverage one.... I've tried 
 

class.wrapper wrap = new class.wrapper();

But i cant seem to figure that one out....i tried to insert and also map<string,string> mapvr = new map<string,string(); refer to the class set var; list<apexpages.message>msgs = apexpages.getmessages(); then mpvr.put(field, data) then trying to force the wrapper by referencing to it directly..

I only need coverage not functionality at this point because that's all been tested and the rest of my test class covers 87% of the functionallity.
