PageNumber is defined as a number, so you should not have [] surrounding PageNumber.  So this: [PageNumber] should be replaced by just PageNumber.

 

Also, where is the definition of PageData?

I removed the [] for both PageNumber in Query 1 and same error. I feel like the error is in the fx because it worked until I changed the fx to use a static URL. Is this what you mean by definition? screenshot below
