Can not set property to null

Ok this probably is stupid question but I've been sitting here trying to fix this issue. I have a select list and when it changes to a specific value i'm trying to set a property to empty string and disable some other fields. Problem is I keep getting the 'TypeError: Cannot set property 'msrp' of null error. I've been looking at this for a while now. Here is the code :

            var msrp;             
            vm.changeDealType = function changeDealType(myScenario, typeId) {

                scenario.isCashDealType = false;
                msrp = '';                          
                if( typeId.value !== null && typeId.value === "Cash"){
                    myScenario.isCashDealType = true;
                    myScenario.original.msrp = msrp;
                }

            };

I've tried your codes, remember you need to send the proper input as required for your function for example:

var myScenario = {};
myScenario.original = {};
var typeId = {};
changeDealType(myScenario, typeId);

You may try with this working code without any errors:

var msrp;

function changeDealType(myScenario, typeId) {

  myScenario.isCashDealType = false;
  msrp = '';
  if (typeId.value !== null && typeId.value === "Cash") {
    myScenario.isCashDealType = true;
    myScenario.original.msrp = msrp;
  }

};

var myScenario = {};
myScenario.original = {};
var typeId = {};
changeDealType(myScenario, typeId);
