Adding Amplitude to a Wix Site

Please do not point me to the documentation. I have read through all of the documentations and they are all missing something for how to actually make Amplitude work on Wix. I have done exactly what this article says, and i have followed both the outdated and the new version of this article. 

I have even added the SDK right into the page code itself and still no dice. Every time i run it i get the “amplitude is not defined” error. It is behaving as though no library of functions is ever called. If i had to guess i need to place something along the lines of “import amplitude from *********” somewhere. Something like this has to be missing from the documentation. If anyone has actually successfully added amplitude to a Wix website would you please show me how?
