I am new to Model Driven Apps. I am trying to Set a field value with the current username when that user Selects Approve on a Choice Column. The research i have done says the only way to do that is to use JavaScript. This is what I have so far after using Copilot:

function GetCurrentUserOnChange(){
var dropdownValue = Xrm.Page.getAttribute("car_BryceCompanyApproval1").getValue();

if (dropdownValue === "Approve") { 
 var currentUserName = Xrm.Utility.getGlobalContext().userSettings.userName;
 var message = currentUserName + "Date and Time";

 Xrm.Page.getAttribute("car_BryceCompany_1_ApproveBy").setValue(message);
}
}

Xrm.Page.data.entity.addOnLoad(hideSectionIfFieldEmpty);

I am not sure if this is the best way to do it. And i am not sure how to get it working with in my form.

Any help would be welcomed.
