I don't know how to order my collection from the movies I have given the lowest scores to, to the highest scores....

In fact, I'm not sure how to use filters at all, I can't find a filter option anywhere... 

You can filter your collection on the "score" you've given it by selecting personal tab of the filters section.  The section titled "Review" is the section you would want.

But what I think what you are asking is how to to sort your list by the review. Click on the little arrow at the top of the collection list and select Review then ascending or descending whichever you prefer. Here's a picture:



Hope this helps.

Thank you antolod - that one seems to work ok.

kahless, I don't have a 'filter' tab at the bottom of my collection list.... 

Found it!

I had to go to View - Window - Filters to put it on, then I managed to make it appear at the bottom next to 'Collection List'

Thanks guys.

hehe - we must have been typing at the same time.
