Displaying words out of a coll?

I have a coll which has stored in it a list of words. I want max to randomly display one of the words in the coll onscreen. However, I can't find a way to do the displaying part of this. All the things like text box require a "set" message sent to them which doesn't itself seem to take an argument which might contain the word which I want to display. Is there anything that can do this? Where I can just get the input out of my coll and display it simply on screen as text?

(Also whenever I get my word out of coll into a message box it is prefaced by the word "symbol"? - any ideas why this might be happening?)
