Automatically spell out any Euro amount entered as a digit in a field for Word.

I have posted a similar question before here, but didn't get to solving it, so here is my current problem: I have a word document for evaluations of art pieces with descriptions and fields, and a macro that inserts an auto text when entering one of these fields (It just inserts more descriptions and fields at the bottom, so I can keep going when i am at the bottom of a page) That all works perfectly fine. Now, the only thing I did not get to work is this: I have an amount that is different for each different art piece, then I have a field (for now) in which I have to type the amount spelled out (so, for example: $40.00, forty USD) I am looking for a way to create the spelled amount automatically after I have populated the field with the digit amount. I know Eric and Graham have given some good suggestions in my previous question, but since I have changed the document completely, and I wasn’t able to re-create what they did, I wanted to ask again for help in here. I have attached the file, so you can see what I have right now but for the macro. Thanks a lot in advance (and I work on Word for Mac 2011).
