Hi @crh0716, I already implemented locally what you suggested. With the templates, what I meant is that I need to load 2 HTML files for this code to work. I solved that by adding an `appendToBodyHTML`, which appends HTML into the body instead of replacing it.

It doesn't seem to be able to select the proper elements doing it this way, so I still get errors. Is that the prpoer way to load 2 external HMTML files? Would it be easier to make a an external 'fake' HTML file and just load that instead of the original ones?
