Generate dynamic HTML file in snaplogic

Hi All,
Have a question:
I have a Script file that generates a dynamic html file.
And this dynamic html file generated is fed into EMAIL SENDER snap.
Problem: I want to place my script file inside snaplogic directly.
Unable to achieve this.
I am pasting my script here:
script.txt (10.4 KB)

If any one can help me how to place the script code into snaplogic.
Tried using script snap but was unable to make it work.
Any help would be much appreciated.
