Hey Harry James Thanks for looking into it. I found it this morning. It was the cache line that I had in there before calling the query.

Ah! Glad to hear you fixed your problem.

I was wondering what that cache line was doing - had to look it up on the Parse Javadocs!

I do like your thinking in this sense though! Do look around at all the awesome stuff Parse has because there is tons (And they are, all awesome).

If there's anything else you get stuck on at some point then please feel free to tag me again! (It helps me learn new stuff too!) :)
