Index Out of Range Error

Question

I have a python script that creates a map series, and I am getting an index out of range error. when I did a check on the elements, the graphic element in question is not showing in the list (see below). The elements are labeled correctly in the mxd and they are populated with data. I am not sure why the element name is not showing when I do the element checker or how to update it.

Instead of adding code as a comment, I suggest you update the original question with the added code.  Doing so would put all the relevant information in the same spot.  Also, don't use screenshots of code, but paste the code and use Posting code with Syntax Highlighting on GeoNet
