I cloned the project and stripped it of some sensitive information which I don't want exposed at this time.
The project can be found here: https://test-22.glitch.me/form/1
I tried with an absolute path '/date.js', relational 'date.js' and what I was initially trying 'js/date.js' (in a folder). But nothing works.
This is my first few days on glitch (having many problems, not too impressed) and just basic knowledge of Node.js with limited experience. I'm assuming all files in the root are served directly from your servers?
Thanks for your help.
