Hi There, as the title says I am just starting to get my head around Apex and triggers. What I am trying to do is create a simple trigger on an Opportunity that will update the owner of that opportunity based on a custom field I have (Opportunity_Sector__c) regardless of who loads the Opportunity

So far I have this but I am getting an error:

trigger OwnerUpdate on Opportunity (before update) {

for (Opportunity o: trigger.new) {
if (o.Opportunity_Sector__c = 'Australasia'){
o.Owner = 'User Name';
    }
  }
}

error is 
Error: Compile Error: Illegal assignment from String to SOBJECT:User at line 5 column 1 

any help here on what I am doing wrong?
