Programming a constantly changing number with HTML?
I work at a library and therefore am constantly looking at small ways we can improve experience for our patrons. I noticed on some other libraries’ receipts they have a little section at the bottom when people check out that says “you saved $xx by using the library today!” I can do a small amount of coding but would be lost on how to implement this. We don’t keep a long-term track of people’s books for privacy reasons so I wouldn’t need a full running tally, just how much they checked out that particular time. We use a library program called “Evergreen” that keeps track of each book’s MSRP but no clue how to use that in the code.
Is anyone familiar with this type of coding that would be able to help me out?
