SHAREPOINT 2010 users
I have a SharePoint List full of items, and one of the field is Topics. I would like to be able to return those values. If I use the actual field Title, I will get [Object Object] as opposed to the object value. I am wondering if it is an issue with the terms I am using since they are so similar to .Net.
Anyways, here is what I have thus far.

The value returned for a lookup column through the JavaScript object model is a compound object (with several properties) instead of a primitive or a string. You might want to access either the ID of the item looked up or the text value of the field being looked up, so it returns both.
Try adding .get_lookupValue() to the end of oListItem.get_item('HRTopics').
Edit:
If the lookup column allows multiple values, the object returned by .get_item() will be an array of objects; the array itself does not support the .get_lookupValue() method. You will need to iterate over the elements in the array and call .get_lookupValue() on each element in order to get the desired values.
var valueString = "";
var values = oListItem.get_item('HRTopics');
for(var i in values){
valueString += values[i].get_lookupValue();
}
