I've been working to create a Lending Library for my organization using Asset Checkout and I'm using 2 SharePoint lists. So far, I've been able to get the flow working in that you can click all the buttons to choose a book, reserve it, and check it out. Where I'm stuck is that, although all the buttons work, when I check the list with all the books (list name: Inventory), all the data stays the same. The book count (CountValue) doesn't change when someone checks out a book and it doesn't say that books with 0 count are unavailable.
My other issue right now is that I can't seem to get my second list updated with who checked out a book (list name: UserCheckout). I basically want this app to work like the Asset Checkout but because I've moved the data sources to SharePoint lists, I had to change the code because of errors that I was getting.
I'm not sure why this page is throwing an error on the days input box.
Also, on the ConfirmationScreen, the ReservedUntil date isn't displaying either.
If anyone can help with this I would really appreciate it. My next step after figuring this out will be to check assets/books back into the tool but I'm hoping it will be a reverse of the checkout process.
