Script help!!

[HowlingMadMurdock]

Hello,

I am working on a script for the company I work for. In short, I am running a report that shows how many days are left for each user (max is 100) and when the user is down to 10 days or less, they will receive an email warning them that they only have 10 days left. I am horrible when it comes to scripting and have limped my way through what I have now but it works. I will share what I completed so far, hopefully someone can help. Thank you
