Text won't load

I have decided to mention this before I figure out how to do it - thinking out loud, as it were, might help me to make sense of it.

So I am going to remove functionality step by step, until I track the source of the problem - I have an array that contains a list of all the text fields, and a pointer to what text it should be displaying, it works on the frames that aren't that complicated.

It also works on my test environment.

So first of all, I will switch off all the php/js type things in the swf, and see if it works then.
